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.
|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.
