1. Nitrile rubber (NBR) is an irregular copolymer synthesized by emulsion polymerization of butadiene and acrylonitrile monomers. Its aging resistance, heat resistance and wear resistance are better than natural rubber. Nitrile rubber is mainly used to manufacture rubber products that work in petroleum-based hydraulic oil, lubricating oil, kerosene and gasoline.
2. Silicone rubber (Si or VMQ) is a linear polymer with a silicon-oxygen bond unit (-si-o-si) as the main chain and an organic group as the side group
Heat-resistant performance Silicone has good high-temperature stability
Strong aging resistance
Good flame retardant performance
Good oil resistance and chemical medium resistance
3. Fluorine rubber (FKM or Vtion), also known as fluorine elastomer, is a high molecular polymer containing fluorine atoms on the main chain and side chain carbon atoms.
Fluorine rubber has excellent heat resistance, ozone resistance and various hydraulic oils
4. Ethylene propylene diene monomer (EPDM) is a terpolymer of ethylene, propylene and a small amount of non-conjugated diene olefins.
EPDM has excellent ozone resistance and good corrosion resistance. The natural color of EPDM is beige and has excellent elasticity.
5. Polytetrafluoroethylene (PTFE)
It is a polymer compound made by polymerizing tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, electrical insulation, good anti-aging resistance, and excellent temperature resistance.
