Synthetic Rubbers

Butadiene Rubber (BR) – High & Low CIS

 Polybutadiene Rubber (BR), the most elastic rubber type, is a polymerized butadiene built up by chemically linking several molecules of butadiene to form giant molecules, or polymers. Polybutadiene Rubbers (BR) are made either with high cis content (95 to 97 percent) or with only 35 percent cis content along with 55 percent trans and 10 percent side vinyl.

Butyl Rubber – (Regular / Chloro & Bromo)

Butyl Rubber (IIR) is a synthetic rubber, a copolymer of isobutylene (98%) with isoprene. The abbreviation IIR stands for Isobutylene Isoprene Rubber (IIR). Butyl rubber (IIR) is characterized by its excellent resistance to ozone. It can be compounded with fillers and other modifiers  and then vulcanized into practical rubber products.

Ethylene Propylene Diene Monomer (EPDM)

Ethylene Propylene Diene Monomer (EPDM) is a type of synthetic rubber produced from a terpolymer of Ethylene, Propylene and a Diene Monomer (EPDM). The ethylene content is around 45% to 85%. The higher the ethylene content, the higher the loading possibilities of the polymer, better mixing, and extrusion. The dienes, typically comprising from 2.5% to 15% by weight of the composition, serve as cross-links when vulcanised with sulphur and resin.

Nitrile Butadiene Rubber (NBR)

Nitrile Butadiene Rubber (NBR), is an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. The more nitrile within the polymer, the higher the resistance to oils but the lower the flexibility of the material.

Polyisoprene Rubber – Staining & Non-Staining (SKI-3S, SKI-3 and SKI-5PM)

Polyisporene Rubber (IR) is manufactured by the polymerization of synthetic isoprene and has the same basic chemical formula as natural rubber (NR). It can be seen as the synthetic version of natural rubber (NR).

Styrene Butadiene Rubbers (SBR)

Styrene Butadiene Rubber (SBR) is composed from a copolymer of styrene and butadiene. Styrene Butadiene Rubber (SBR) is a durable and economical rubber, which can be used in a wide-range of industrial applications.

Chloroprene Rubber (CR)

Chloroprene Rubber (CR), also known as chlorobutadiene rubber, is an important diene-based elastomer. The commercial grades are mostly trans-1,4-polychloroprene produced by free-radical emulsion polymerization of 2-chloro-1,3-butadiene.
