Materials

Natural Rubber (NR)
Chemical Structure: Polyisoprene
Mechanical properties such as the elasticity, wear and abrasion resistance are good.
Nitrile Butadiene Rubber (NBR)
Chemical Structure: Butadiene-acrylonitrile copolymer

Oil, wear, abrasion, and aging resistance are good.
Hydrogenated Nitril-butadiene rubber (HNBR)
Chemical Structure: Butadiene-acrylonitrile copolymer (hydrogenated)
Good oil resistance, abrasion resistance, aging resistance and weather resistance(Oxidation, Ozone, UV)
Styrene-Butadiene Rubber (SBR)
Chemical Structure: Butadiene Styrene copolymer
Wear, abrasion, and aging resistance are better than natural rubber.
Butadiene Rubber (BR)
Chemical Structure: Polybutadiene
Elasticity is good. Wear and abrasion resistance are also superior to natural rubber.
Chloroprene Rubber (CR)
Chemical Structure: Poly chloroprene
Weatherability, ozone resistance, heat resistance, and chemical resistance, are excellent.
Isobutylene-Isoprene Rubber (IIR)
Chemical Structure: Isobutylene isoprene copolymer
Weatherability, ozone resistance, and gas-proof permeability are good, and bears a polar solvent.
Ethylene-Propylene (EPM, EPDM)
Chemical Structure: Ethylene proplene copolymer
Aging resistance, ozone resistance, the resistance to a polar liquid and electric nature are good.
Acrylic Rubber (ACM ANM)
Chemical Structure: Acrylic ester copolymer
Good for high temperature oil resistance.
Urethane Rubber (U)
Chemical Structure: Polyurethane
Polyurethane excels in dynamic intensity. Polyurethane has good biocompatibility and is commonly used in biomedical devices.
Silicone Rubber (VMQ)
Chemical Structure: An organic polysiloxane
Silicone has excellent resistance to heat and cold. Oil resistance is also good. Silicone has very good biocompatibility, making it a preferred choice for medical device.
Fluorocarbon Rubber (FKM)
Chemical Structure: Perfluoropropene, vinylidene fluoride copolymer
This rubber material has the highest resistance to heat and cold.
