Tires and tubes, gasket, belt, hose, seals, shock mount

Tires and tubes, gasket, belt, hose, seals, shock mount

Usually blended with other Elastomer to provide resilience better low temperature properties and abrasion resistance

Tires and tubes, gasket, belt, hose, seals, shock mount

Vehicle inner tubes, steam hose, flexible electrical insulation, shock and vibration absorbers

Auto parts, electrical insulaiton, dust covers, weather stripping and conveyor belts

Petroleum and chemical tank linings, automotive gaskets and seals, molded parts, footwear and weatherstripping

White or colored parts, spark plug covers, seals, gaskets, hose and  wire insulation

Solid tires, snowmobile tracks, grease seals, hydraulic accumulator diaphragms

Parts subjected to extremely high or low temperatures, sealss, gaskets, o-rings and bellows

O-rings, shaft seals, valve parts, packings, diaphragms, gaskets and pump parts
