Rubber is a kind of polymer material with high elasticity, different products have different requirements for different rubber, these requirements have resistance to strength, aging, high and low temperature, oil and so on.The properties of rubber mainly depend on the types of raw rubber used and the different formulations of rubber materials.

Natural rubber (NR) has excellent resilience and is mainly used in tyres, shock absorber pads, flat rubber pads and seals.

Neoprene (CR), good adhesion with metal and fabric, suitable for making sealing ring and sealing profile, extrusion hose, coating, wire insulation layer and making adhesive, etc.

Ethylene propylene rubber (EPM, EPDM) is relatively resistant to phosphate oil, acid and alkali, rocket fuel and oxidant.Suitable for making gromlins, extruded rubber pipes, doors and Windows of airplanes and automobiles, rubber gaskets for automobiles, tapes and insulation layers for wires.But products are not resistant to petroleum-based oils.
