Stress-Strain Behavior of Polymeric Elastomers

JHUS tress- strain Behavior of Polymeric ElastomersA Polymeric elastomer is defined by the American Society for Testing and Materials (ASTM)as a material that, at room temperature, can be stretched repeatedly to at least twice its originallength, and, upon immediate release of the stretch, will return with force to its approximateoriginal length . First developed in Germany in 1937, production of (polyurethane) elastomericfibers has increased in demand over the last forty years, primarily due to the development offibers that can move with and physically support the human Elastomers chemically con-Figure 1: Virtual crosslinks formed by attractionsbetween hard blocks in a Polymeric of long, randomly coiled domains ofaliphatic polyethers or polyesters, joinedby stiff regions of urethane linkages.
