Rubber Testing

Rubber is a resilient, elastic polymer, which is used for manufacturing of products as diverse as car and bicycle tires, buffer blocks, windshield wipers, hoses, seals, mattresses, and many other things. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is harvested mainly in the form of the latex from the rubber tree (Hevea brasiliensis), rubber grass and other plants. The latex then is refined into the rubber that is ready for commercial processing. The synthetic rubber is obtained by the polymerization reaction of various monomers.

Common types of rubber include natural rubber (SPR), silicone rubber Q, fluorine rubber (FPM), isobutene-isoprene rubber (IIR), styrene butadiene rubber (SBR), chloroprene rubber (CR), ethylene propylene rubber (EPR), nitrile butadiene rubber (NBR) and Viton (FKM)

STEMart provides a wide range of lab testing services for various rubber products and advise you on the best standard testing package for your products.
