Synthetic Rubber

Synthetic rubber, invariably a polymer, is any type of artificial elastomer mainly synthesised from petroleum by-products. Synthetic rubber, like natural rubber, finds wide applications in the automotive industry for tires, door and window profiles, hoses, belts, matting, and flooring etc.

A Series of chemical additives like Antioxidants, coagulants and emulsifiers are developed by KAPL to impart a set of properties including heat, color and processing stability, resistance to oxidation, cohesion, endurance to heat among many to ensure better product lifetime.

1. ANTIOXIDANTS TNPP series products are secondary antioxidants / heat stabilizers used in the manufacturing of synthetic rubber such as SBR, E-SBR, PBR, NBR. They enhance the heat, colour and processing stability of rubber.

Cristol SP is a non-staining and non- discoloring general purpose antioxidant for dry rubber and latex compounds. It finds wide applications in white & light colored latex and rubber applications such as flooring, sports goods, shoe soles, general mechanical goods, carpet backing etc.

2. COAGULANTS They are polymeric coagulants of relatively low molecular weight, to allow rapid diffusion in the medium and around the particles and have a very high cationic charge to neutralize the negative charges of the colloids.
They are very effective in emulsion breaking and production of rubber from latex.
  • Effective separation of polymer and aqueous layers.
  • Lower dosage levels.
  • Clarity of aqueous layer / mother liquor.
  • Effective coagulation and faster settling.

3. EMULSIFIERS Disproportionated rosin which is derived from high-purity rosin through catalytic reaction at proper temperatures is used as an emulsifier in the production of synthetic rubber.

Using DPR as an emulsifier, rubber product will improve in cohesion and the endurance to heat will increase for 25%. The endurance to both abrasion and laceration of this rubber is better than ordinary styrene-butadiene rubber.

  • Improved Cohesion
  • Increased endurance to heat
