Carbon Black
Carbon Black

We offer highly pure Carbon black which is material produced by the incomplete in combustion of heavy petroleum products such as FCC tar , Coal Tar ,Ethylene Cracking tar ,and a small amount of vegetable oil, An amorphous carbon with a high surface area to volume ration and nano that find common use similar to soot , it has got much higher surface area to volume ratio.

We offer various grade of Carbon Black manufactured from Indian Co Like PHILIPPS/HI-TECH/CONTINENTAL CARBON & imported also from RUSSIA /IIRAN/CHAINA

Grade are as under:
  • SF - 220
  • HAF -330
  • FEF - 550
  • GPF -660
  • SRF -774
Use:
  • Used as a pigment and reinforcement in rubber and plastic products
  • Reinforcing phase in automobile tires
  • Conducts heat away from the tread and belt area of the tyre
  • Reduces thermal damage and increasing tire life
  • Additive E153 is used as a food coloring agent



Stearic Acid
Stearic Acid

We offer Stearic Acid which is one of the useful saturated fatty acids extracted form animal and vegetable fats and oils. The salts and esters of stearic acid are called stearates and is useful in:
  • Softening rubber
  • Soap
  • Plastic
  • Cosmetic Candle making
  • Added to the product in molten form and allowed to crystallize under controlled conditions
  • Used to coat metal powders such as aluminum and iron preventing oxidation allows compositions to be stored for longer
  • Hardener in candies
  • Parting compound in making plaster castings from a plaster piece mold or waste mold
  • Esters of stearic acid with ethylene glycol, glycol stearate and glycol distearate  used to produce a pearly effect in shampoos, soaps,and other cosmetic products
These are available in the following grade :
  • LUBSTRIC / RUBBER GRADE
  • DISTRIC
  • PHARMA GRADE



Natural Rubber
Natural Rubber

Exporting superior quality Natural Rubber, we offer a highly efficient chemical and occur as a milky colloidal suspension in the sap of some plants. The entropy model of rubber was developed in 1934 by Werner Kuhn. Synthetic rubbers are made by the polymerization of a single monomer or a mixture of monomers to produce polymers.
  • RMA
  • RSS IV
  • RSS V
  • RSS IX
  • ISNR
  • EBC
  • LATEX



Synthetic Rubber
Synthetic Rubber

We supply a wide range of Synthetic Rubber made form polymer material and act as an elastomer that can undergo much more elastic deformation. It serves as substitute for natural rubber in many cases, especially when improved material properties are needed. Synthetic rubber can be made from the polymerization of a variety of monomers including isoprene (2-methyl-1,3- butadiene), 1,3-butadiene, chloroprene (2-chloro-1,3-butadiene), and isobutylene (methylpropene) with a small percentage of isoprene for cross-linking.

  • SBR -1502 & 1712
  • PBR-1220 / 01
  • NBR-KNB 35L
  • SILICONE
  • BUTYLE
  • NEOPRENE
  • EVA
  • EPDM



Reclaim Rubber
Reclaim Rubber

Reclaim prodyces reclaim rubber front scrap of whole tyres, tread peel! tubes, butyl tubes, colored rubber products etc for different a non tyres rubber products. Since robber content of tyres produced in natural rubber, reclaim from India has its own special characteristics.

We offer to our client's superior grade of oils for processing rubber. Manufactured using advanced production techniques, they are available in three grades:
  • It is a para fin type of rubber processing oil that is recommended for extruded articles, Hawaii slippers, tyre tube and many more.
  • It is a napthanic type of rubber processing oil that is recommended for LPG tube, Hawaii chappal and other similar products.
  • It is an aromatic type of rubber process oil that is recommended for tyres, molded articles and other similar applications.



Chemical Solvents
Chemical Solvents

Our range of DOP / DBP / Solvents is a clear, water-insoluble liquid with the typical smell of paint thinners possessing a sweet smell of the related compound benzene. It was firs isolated from Colombian tree Myroxylon balsamum and used as:
  • An industrial feedstock
  • Solvent to dissolve: Rubber, paints, paint thinners, silicone sealants,[6] many chemical reactants, rubber printing ink, adhesives (glues), lacquers, leather tanners, and disinfectants
  • Fullerene  indicator
  • An inhalant drug for its intoxicating activity
  • Carbon source for making Multi-Wall Carbon Nanotubes
  • Breaking open red blood cells in order to extract hemoglobin in biochemistry experiments
  • Octane booster in gasoline fuels used in internal combustion engines
Reacting as a normal aromatic hydrocarbon towards electrophilic aromatic substitution, it is made 25 times more reactive than benzene and undergoes smooth sulfonation to give ptoluenesulfonic acid. Moreover, undergoes nitration to give ortho and para nitrotoluene isomers and on heating give dinitrotoluene and ultimately the explosive trinitrotoluene (TNT).
