Elastomeric polyurethanes are a class of material with similar characteristics to that of rubber. As well as being highly elastic this material boasts good abrasion resistance, tear strength, a wide temperature stability range and good resistance to chemicals. Elastomer polyurethanes are commonly used in situations where moisture barrier is required.

Hardness values range from 20 shore A to 80 shore D and its superior elasticity properties allow some elastomer polyurethanes to stretch to six times original size. These materials also have a great shape memory enabling the product to return to its original shape after distortion.
