Zinc stearate (ZS)
Zinc Stearate is an oleochemical substance featuring a white, powdery appearance. Zinc Stearate has the ability to resist water and is insoluble in certain types of polar solvents. Zinc Stearate is formed by combining stearic acid with zinc oxide, the latter of which is an organic white-powder compound that is insoluble in water. While it does not produce a strong odour, Zinc Stearate powder does have a slight fatty acid scent.

There are many methods to manufacture Zinc Stearate. In addition to the direct method of combining stearic acid with zinc oxide, there is also an indirect method known as precipitation, which entails the formation of a solid from a liquid solution. The fusion method involves a high-shear process using tightly controlled pressure and temperature conditions.

Zinc Stearate offers a number of chemical properties that are invaluable from a manufacturing perspective.

Coloration of Plastics is a key process which is mainly carried out to improve Plastics’ aesthetics and to enhance Plastics’ performance in use.

Pigments are of two types: organic and inorganic. Organic pigments are brighter, purer, and richer in colour than inorganic pigments; however, they are more susceptible to ultraviolet radiation damage, chemical damage, and colour bleeding. Also, organic pigments are translucent and therefore do not add to the hiding ability of the paint. Inorganic pigments are considered hiding or semi hiding pigments and are low priced. However, the colours of inorganic pigments tend to be earthy and muddy.

Types of Pigments
Based on the method of their formulation, pigments can be categorized into two types: inorganic pigments and organic pigments.

Organic Pigments Inorganic Pigments

Organic Pigments
This type of pigments occurs naturally and they’ve been used for centuries. They’re quite simple in their chemical structure. They’re named organic as they contain minerals and metals that give them their colour. Organic pigment manufacturers produce them through a simple process that’s made of washing, drying, powdering and combining into a formulation.

Compared to inorganic pigments, this usage of these pigments is less frequent and that’s why there are limited number of organic pigment suppliers. These pigments are used when the required colour strength isn’t too much.

Sudarshan Chemical Industries Ltd India
Ferro Corporation US
Trust Chem Co. Ltd China
Dainichiseika Color & Chemicals Mfg. Co. Ltd Japan
DCL Corporation Canada
Toyocolor Co. Ltd Japan

* List is not exhaustive

Inorganic Pigments
As you can guess by its name, this type of pigments is exactly the opposite type of organic pigments. These pigments are also known as “synthetic pigments.” They’re formulized in labs and offer great scope of control to inorganic pigment manufacturers. Inorganic pigments are manufactured by relatively simple chemical processes such as oxidation.

Inorganic pigment mainly gets used in plastics, paints, synthetic fibers and ink industry. It is useful where bright colours are required, organic pigments are used as they bolster high colour strength. Inorganic pigments include white opaque pigments which are commonly used to lighten other colours and also to provide opacity.

DOP & Epoxy

Plasticiser are low molecular weight substances that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, or to decrease friction during its handling in manufacture. Plasticizers are added to a polymer solution to promote its plasticity and flexibility.

Plasticizers are colourless and odourless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride), plasticizers soften the PVC to make it flexible and bendable.

Plasticizers available at SNG Microns Private Limited

Epoxidized soybean oil (ESBO) Di-n-octyl phthalate (DOP)

Epoxidized soybean oil (ESBO)

Epoxidized soybean oil (ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a yellowish viscous liquid. Commonly known as epoxy oil in PVC pipe & fittings industry.

ESBO is used as a co-stabilizer and plasticizer in flexible as well as rigid PVC applications. It not only improves colour hold but also increases weathering properties. Our ESBO can be used in various applications such as Pipe, wires and cables and rigid extruded products to enhance thermal and aesthetic properties.

We suggest customers to check the technical data sheet (TDS) of product before placing order to suppliers to optimize their production and to get complete benefits of original products.

Di-n-octyl phthalate (DOP)
Di-n-octyl phthalate appears as a clear liquid with a mild odour. Slightly less dense than water and insoluble in water. Hence floats on water. Di-n-octyl phthalate is a colourless, odourless, oily liquid that doesn’t evaporate easily. It is a man-made substance used to keep plastics soft or more flexible. This type of plastic can be used for PVC Pipe, medical tubing and blood storage bags, wire and cables, carpet back coating, floor tile, and adhesives. It is also used in cosmetics and pesticides.

The mixing of polyvinyl chloride (PVC) with dioctyl phthalate (DOP) shows two stages of gelation and fusion, but the homogeneity of each stage is influenced by the thermal stability of PVC and its rheological behaviour. Hence help in making pipe soft or more flexible.

Why Other plasticizer are cheaper Or Another supplier offering at cheaper rate?

World produces various type of plasticizers for varies industries, all the plasticizers produced across globe or in India are not same, based on physical and chemicals property, different plasticizers get used in different applications. Similarly for PVC Pipe, fittings or plastic industry there are many plasticizers available in the market for applications. In-fact the “filler” of plasticizer is also available in market which are cheap, low- cost, of inferior quality. While buying, you could observe that on drum of plasticizer either “Plasticizer” is mentioned or nothing is mentioned as product name or something else is mentioned on packetizing or invoice.

Very few suppliers offer DOP or Epoxidized soybean oil. The trick in the market is that when customer place an order for DOP or Epoxidized soybean oil, suppliers accept the order and they supply just any plasticizer, which are generally “filler” of plasticizers and of lower quality. However, suppliers offer just slightly lower price quotation so that customer can not judge of quality based on price, We at SNG Microns Pvt Ltd receive almost daily inquiry on our price of DOP and Epoxidized soybean oil being much higher but we know that supplier offered lower price to customers are not supplying the original DOP or Epoxidized soybean oil as per technical standards, they are just supplying any plasticizers.

Not only, what we have mentioned above, it is also that supplier is billing DOP and Epoxidized soybean oil in invoice but giving the customer Chlorinated Paraffin Oil (CPW) oils, which is much cheaper compare to DOP and Epoxy.

Where to buy from ESBO and DOP
We are one of the largest suppliers of ESBO and DOP, you could blindly trust us on quality of products and price.

Key benefits of MBS

Good impact strength Good gloss Excellent weatherability

Applications of Impact Modifiers
For U-PVC pipes in India, if fusion is optimized, addition of impact modifiers is not necessary for pipes not exposed to severe weather conditions. However, for profiles having sharp corners and window profiles exposed to solar radiation, impact modifier is necessary.

Impact modifiers are used for long term use of PVC/C-PVC products especially under cold conditions and outdoor exposure. C-PVC pipes used for conveying hot water from solar heaters or geysers are usually exposed to solar radiation and weathering. Therefore, impact modifiers shall be judiciously selected for C-PVC pipes for indoor and outdoor use.

Impact Modifiers are recommended for being used in PVC formulations for a wide range of applications such as:

Paint Driers

What does Drier Mean? Driers are various compounds added to paints and coatings intended to decrease the drying time of the paint or coating. Driers help corrosive paints improve their drying characteristics even at low temperatures and in humid atmospheres.

Driers are important additives for paints & coatings as they speed up the autoxidation procedure. Without these drying substances the cross-linking process slows down, allowing the paint layer to dry only after few months post application. With driers the formation of a firm film is achieved generally within a few hours after paint application.

The main function of a drier is to quicken the drying of linseed oil in the paint and in consequence paint film becomes hard. Paint film gets hardened as drier absorbs oxygen from the air & transfer it to the linseed oil.

Driers are mainly metal octoates and naphthenates and the role of the drier is determined mostly by the metal constituent of the drier compound, such as cobalt octoate. Cobalt is the utmost active drying substance at ambient drying conditions. Still, other driers play an essential role in film hardness and performance.

Key features of Paint Driers

  1. Quicken drying procedure
  2. Easily soluble
  3. Required in small quantity
  4. To be added just before use
  5. Compatible with paint

Types of Paint Driers

Primary or Active Driers Secondary or Auxiliary or Through Driers Combination of driers

Primary or Active Driers
Primary driers are autoxidation catalysts, and as such function predominantly as surface driers, where the dioxygen concentration is highest. It is most unusual to use a main drier in a coating formulation without a supplementary secondary or auxiliary drier.

Secondary or Auxiliary or Through Driers
Secondary driers are active in the cross-linking steps of drying, they are accountable for overall drying throughout the entire paint layer. These driers link fatty acid chains via oxygen-metal-oxygen bridges which leads to cross-links.

Combination of Driers
It is a combination of primary, through & auxiliary driers that provide even and fast drying. It also reduces the chance of batch disparity.

Benefits of using a Combination Drier

  • Storage Stability, avoiding degradation
  • Simplified handling and dosing
  • Stock only one Drier
  • Easier logistic control
  • Lower VOC – avoid the addition of unnecessary extra solvents

Why to buy from SNG Microns Private Limited
We at SNG Microns Private Limited offers driers with very high purity and consistent viscocity that ensures consistent performance in terms of drying time and properties of the paint film after complete drying. Connect wit us for wide ranges of paint drier available with us.

Titanium Di-oxide

Titanium dioxide, also called titania, (TiO2), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity. Titanium, the ninth most common element in the Earth’s crust, Titanium naturally interacts with oxygen to form titanium oxides, commonly found in ores, indigenous dusts, sands and soils. Pure titanium dioxide is a fine, white powder that provides a bright, white pigment.

Type of Titanium Di-oxide

Rutile Anatase

Available Grade of Titanium Di-oxide at SNG Microns Private Limited

Type Manufacturing Process
Rutile chloride process, sulfate process
Anatase sulfate process

Manufacturing Process of Titanium Di-oxide
Method of manufacture Commercial titanium dioxide pigment is produced by either the sulfate process or the chloride process. Because of significant environmental and cost issues associated with the sulfate process, most new manufacturing capacity is based on the chloride process. Older manufacturing plants that used the sulfate process have had to modify their processes to accommodate stricter environmental requirements by recycling waste acids and roasting metal sulfates to recover sulfur trioxide The principal raw materials for manufacturing titanium dioxide include ilmenite, naturally occurring rutile, and titanium slag. The last is produced by removing the iron from ilmenite by reduction with coke at 1200-1600 ° C. At these temperatures, the iron oxide is reduced to the metal, which melts and separates from the formed titanium-containing slag, which is 70- 75% titanium dioxide Among its many useful qualities, TiO2’s refractive properties, durability and brilliance of colour make it an ideal additive to plastics used outdoors, as it gives them a vital hardiness to withstand weathering and light damage.

The sulfate Process
Both anatase and rutile grades of titanium dioxide can be produced by the sulfate process, depending on particular processing conditions. Briefly, ilmenite or ilmenite and titanium slag is digested with sulfuric acid and the product is diluted with water or dilute acid. Most of the titanium dioxide from the ore is solubilized as a titanium oxo-sulfate and iron is present in its +II oxidation state. The resulting liquor is clarified by sedimentation to remove insoluble residues such as silica. Iron is removed by crystallization as its sulfate salt, followed by filtration.

To produce the anatase form of the titanium dioxide, a small portion of the clarified liquor is neutralized with alkali to produce anatase microcrystals. These microcrystals are then introduced into the mother liquor, which is then hydrolysed under carefully controlled conditions to produce crystals of anatase. These are subsequently filtered, washed, calcined, and micronized. During calcination, the final temperature reaches about 800-850 ° C. To produce the rutile form of the titanium dioxide, the clarified liquor is hydrolyzed in the presence of a specially prepared rutile seeding agent obtained by neutralizing a small portion of the mother liquor in the presence of hydrochloric acid or some other monohydric acid. Formed crystals are filtered, washed and calcined at temperatures between 900 and 930 ° C, and micronized.

Chloride Process
The chloride process yields the rutile form of titanium dioxide. At temperatures between 800 and 1200 ° C, chlorine is reacted in a fluidized bed reactor with a titanium-containing mineral, e.g., mineral rutile (which is not readily attacked by sulfuric acid), under reducing conditions (presence of coke) to form anhydrous titanium chloride. Purification of the anhydrous tetrachloride requires separation by fractional condensation. Conversion of the tetrachloride to titanium dioxide may be accomplished by either direct thermal oxidation or reaction with steam in the vapour phase at temperatures in the range of 900-1400 ° C. A minor amount of aluminium chloride is generally added to promote formation of the rutile form. The titanium dioxide is washed, calcined, and packaged. Alternatively, the titanium-containing mineral can be reacted with concentrated hydrochloric acid to form solutions of titanium chloride which are then further purified. Hydrolysis of the tetrachloride will yield the dioxide which is filtered off, washed, calcined, and packaged

Application of Titanium Di-oxide
Titanium dioxide has been used for a century in a range of industrial and consumer products, including plastics, paints, coatings, adhesives, paper and rubber, printing inks, coated fabrics and textiles, as well as ceramics, floor coverings, roofing materials, cosmetics, toothpaste, soap, water treatment agents, pharmaceuticals, food colorants, automotive products, sunscreen and catalysts.

Titanium dioxide is particularly found in the universally used product Polyvinyl Chloride – more commonly known as PVC. PVC is renowned for its durable and resistant nature and is used for a large range of outdoor plastic-based products.

TiO2, used within PVC, helps to ensure the protection of outdoor pipes that provide a vital role to homes and developments, for example, electricity, water and gas supplies. It has been estimated that the use of PVC piping can be maintained for up to 100 years

They include higher alkanes and lipids, typically with melting points above about 40 °C, melting to give low viscosity liquids. Waxes are insoluble in water but soluble in organic, nonpolar solvents. Natural waxes of different types are produced by plants and animals and occur in petroleum.

Type of Waxes used in PVC Plastic (Pipe & fittings); available at SNG Microns Private Limited

Polyethylene wax

Paraffin Wax

Hydrocarbon Wax

 Polyethylene wax (PE Wax)
PE WAX is polyethylene homopolymer wax; an ultra-low molecular weight polyethylene consisting of ethylene monomer chains, an excellent and consistent ingredient for end formulations to improve product physical appearance and thermal properties for a broad range of industries, including hot melt adhesives, PVC, colour masterbatches, rubber and thermoplastics road markings, etc

PE wax is derived from ethylene through a process called polymerization. Manufacturers alter the polymerization process to get a product with desired qualities. However, certain basic properties of the material are common for all PE wax. polyethylene wax is linear and crystalline. That is why this material finds applications such as blends, plastic additives and rubber manufacture

PE wax is heat-stable, lowly soluble, chemically resistant and hard. Combining these features with abrasion resistance and broad melting points makes the material the undisputable choice for a wide range of industrial applications

Paraffin Wax
Paraffin wax is mostly found as a white, odourless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C. Paraffin wax was first created in 1830 by the German chemist Karl von Reichenbach when he tried to develop the means to efficiently separate and refine the waxy substances naturally occurring in petroleum.

Paraffin wax which was first produced commercially in 1867, within 10 years after the first petroleum well was drilled. Paraffin wax precipitates readily from petroleum on chilling. Technical progress has served only to make the separations and filtration more efficient and economical. Purification methods consist of chemical treatment, decolorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both. Crude oils differ widely in wax content.

Hydrocarbon wax (HC wax)
Hydrocarbon wax (HC wax) is an excellent external lubricant for PVC Processing. PVC has natural tendency of sticking to metal at the time of processing and hence it is not lubricated externally and as such the extrusion results are not satisfactory.

By using HC Wax as a Lubricant, one will achieve higher rate of production, shining smooth internal and external surface.

Application of Wax
Wax has many physical and chemical properties that make it suitable for a wide range of industrial applications. Like PVC pipes -fitting, CPVC pipe-fitting, uPVC pipes-fittings, PVC clothing, PVC furniture, PVC flooring, PVC door-window, PVC footwear, PVC blister film, PVC rigid sheet, PVC flexible film, PVC packaging film, PVC lamination film, PVC stretch film, PVC shrink film, PVC celuka foam board/sheet, WPC sheet, WPC profiles/chokhat, PVC free foam sheet, advertising flex banner, PVC suction-garden tube, PVC rigid/flexible profiles, automotive products and many other application like Masterbatch, textile finishing, cosmetics, polishes, paper coating, leather auxiliaries, adhesives, carriers for pigment concentrates, and in paints and printing ink industry. Plastic, Candles, Packaging, Coatings & Polishing, Hot Melt Adhesive, Tire & Rubber, Cosmetics & Personal Care, Food, Others.

 Why to buy wax from SNG Microns Private Limited
We not only directly source the materials from Indian manufactures but also import from world largest manufactures. There are many unrefined or semi-refined waxes in the market sold by various traders which have more oil contents or hardness. Our wax colour is super white. When you touch it with your hands, give you feel of good smoothness. It feels like plastic rather than wax. It is hard, brittle, fragile, and does not form a mass at room temperature. Paraffin; containing high impurity or oil are greasy, greasy to the touch, feel like touching candles, soft and sticky. If you hold them with your hands, they will form a ball. The genuine product smells like plastic, while breaking the flake of PE Wax, it gives crack sound while inferior quality just soften while breaking or break with low sound.

Stearic Acid

Stearic Acid is a saturated long-chain fatty acid with an 18-carbon backbone. It is another name for octadecanoic acid. Stearic acid is found in various animal and plant fats. Stearic acid is a white solid with a mild odour, floats on water. Commercial stearic acid is a mixture of approximately equal amounts of stearic and palmitic acids and small amounts of oleic acid. The pure acid undergoes chemical reactions typical of carboxylic acids. It is a colourless, waxy solid that is almost insoluble in water. In purified form it presents as shiny white flakes or powder.

Palm derivatives Stearic Acid which are used in PVC, cosmetics, rubber, textiles, and candle manufacturing industries melting point of 69.6 ° C and is a major component of animal and vegetable fats.

Application of Stearic Acid

Stearic acid in the plastics industry is widely used in the manufacture of PVC plastic pipes, sheets, profiles and films. It is a PVC heat stabilizer with good lubricity and good light and heat stability.

In plastic PVC pipes, stearic acid help prevent “scorching” during processing. Adding it is an effective thermal stabilizer in the processing of PVC films, and it can prevent the violent exposure to sulfide discoloration of the finished film.

Stearic acid is mainly used in the production of stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminium stearate, cadmium stearate, iron stearate, stearic acid Potassium, widely used in cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and other organic chemicals.

In plastic PVC pipe, stearic acid helps to prevent “coking” during processing.

In the rubber industry, stearic acid plays a vital role in the synthesis and processing of rubber. Stearic acid is an active vulcanization agent widely used in natural rubber, synthetic rubber and latex, and can also be used as a plasticizer and a softener. Stearic acid is used as an emulsifier in the production of synthetic rubber. Stearic acid can be used as a foaming agent in the manufacture of foam rubber, and stearic acid can also be used as a release agent for rubber products.

In the cosmetics industry, stearic acid is used in emulsification in creams and cold creams to make it a stable whitening cream. Stearic acid soap esters are more widely used in the cosmetic industry.

Distribution and Buying Patterns of Stearic Acid
Most of manufactures have appointed their dealership across India, however few of them offers directly to customers on case-to-case basis. As the consumption in PVC Pipe & Fitting industry is limited, there is no credit facility given by manufactures, hence trader/ wholesaler has to buy against payment. In eastern India, there is only one manufactures, but known for producing less C18% of Stearic Acid. Hence, we source from manufactures who have built reputation over times across not only in India but globally.

How to choose Stearic Acid for PVC Pipe & Fittings / Plastic Industries
Knowing C18 is the most critical data before you buy stearic acid for plastic industries. In India, almost all manufactures do not disclose the C18 in their technical data sheet. Percentage of C18 is kept hide to mislead the buyers, We at SNG Microns Pvt Ltd discussed the C18% (Stearic Acid percentage) with our customers. When you get the quote which is lower than other suppliers, be assured that the quality of product will not be good as C18% would be less in that. Not only this, even many of suppliers offers rubber grade stearic acid to PVC Pipe manufactures and charges the price of plastic grade stearic acid, this not only decrease the performance of machine but also decrease the life of machine and finished products.

Why to buy from SNG Microns Private Limited
At SNG Microns Pvt Ltd, we discussed with customers and understand their requirements before quoting the price of specific grade. Our customers are loyal towards us as we have built trust with them overtime on quality of products. We proudly say that we have zero complaints on our product portfolio.
