WebApr 24, 2001 · Introduction. Elasticity is a property possessed by many solid materials, but the class of materials known as rubbers or elastomers possess a different property called high elasticity. This differs from conventional Hookean elasticity in that it exhibits much higher values of elongation at break, up to 1000% or more. http://bipcons.ce.tuiasi.ro/Archive/369.pdf

WebACM. ACM elastomers offer excellent heat resistance; they can typically be used at temperatures of 150°C (up to 175°C for limited periods). They provide high resistance to oxygen, ozone and industrial oils. Resistance to water is generally poor, and compression set and low temperature flexibility depend on base polymer and compounding choice. WebAn elastomer is a polymer with high elasticity due to its coiled structure. A typical elastomer is nonvulcanized rubber, where the chains are first unkinked when a stress is applied, followed by chain straightening and lengthening. Elastomers are poorly crystallized but become more crystalline as they are stretched.
