ABSTRACT
An elastomer is generally considered to be any material, either natural or synthetic, that is elastic or resilent and in general resembles natural rubber in feeling and appearance. A more technical definition is provided by ASTM, which states, “An elastomer is a polymeric material which at room temperature can be stretched to at least twice its original length and upon immediate release of the stress will return quickly to its original length.” These materials are sometimes referred to as rubbers.
