SBR have very good abrasion resistance,good mechanical properties, good heat and aging resistance,good electrical propperties,and good resistance to polar solvents,acid and base solution.
Silicone rubbers have excellent resistance to ozone,oxidation and UV light.They also have very good resistance to moisture and weathering. The flexibility properties is very good.
NBR have very good resistance to liquid fule mineral oils and greases,good resistance to aging ,high resistance to wear and abrasion low permeability and good physiological properties.
Urethane rubber have hight tensile strength and abrasion resistance.They are good oil and tear resistance .The flexibility properties can vary depend on the formulation.
EPDM have excellent resistance to weathering and ozone good to very good aging resistance,and low temperature flexibility ,low electrical conductivity and satisfactory resistance to polar chemicals.
Fluoroelastomers are specialty elastomer have excellent heat resis tance,excellence resistance to aggressive juels and chemical.They have very good mechanical,physical properties,wear and abrasion resistance.
