Natural rubber is a polymer made up of the organic component isoprene, extracted from the bark of tropical and subtropical trees. Latex is a milky colloidal emulsion of rubber, proteins, fatty acids, resins, and water. Latex is derived from the tree, Hevea Brasiliensis. (Reference)
Styrene-butadiene rubber (SBR) refers to a group of synthetic rubbers derived from styrene and butadiene. These materials have excellent abrasion resistance and aging stability with the protection of additives. The ratio between styrene and butadiene influences the rubber properties. (Reference)
EPDM is a type of synthetic rubber made from ethylene, propylene, and a diene comonomer that enables crosslinking via sulfur vulcanization. Typically used dienes in the manufacture of EPDM rubbers are ethylidene norbornene (ENB), dicyclopentadiene (DCPD), and vinyl norbornene (VNB). (Reference)
Chloroprene rubber (CR) is a synthetic rubber that is also known by the trade name Neoprene. CR has a good balance of properties, including good chemical stability and usefulness over a wide temperature range. (Reference)
Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. This rubber is unusual in being resistant to oil, fuel, and other chemicals. (Reference)
Valued for their electrical-insulating properties, chemical stability, and the wide temperature range over which they retain resiliency, silicone rubbers are used mainly in O-rings, heat-resistant seals, caulks, gaskets, electrical insulators, flexible molds, and (owing to their chemical inertness) surgical implants.

FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. FKM is an abbreviation of Fluorine Kautschuk Material. Fluoroelastomers provide excellent high temperature (up to 500°F or 260°C) and aggressive fluids resistance when compared with other elastomers, while combining the most effective stability to many sorts of chemicals and fluids such as oil, diesel, ethanol mix or body fluid.
