(B) A representation of elastomers cured with (left) and without (right) an applied field during curing. Chapter-2 reviews swelling elastomers and their uses in different petroleum applications. An elastomer is a rubbery material composed of long chainlike molecules—polymers. 51 Billion in 2017 to USD 7. When elastomers are compared for such properties as tensile strength, coefficient of friction, and abrasion resistance, they show similar results if tested at equal values of T−T g, where T is the test temperature. Hydraulic damping on every pedal, custom made elastomers for a progressive brake feel.
