Urethane/Polyurethane is a term used to describe a family of elastomers (any compound exhibiting the characteristics of natural rubber; stretchy and elastic). Poly meaning “many” and “urethane” denotes the classification of the chemical structure. Polyurethane or Urethane for short is used as a solid cast material (bushings, mounts, mount inserts, etc.) that can be compounded as soft as a rubber band or as hard as a bowling ball. Each of our products is specially formed to exact specifications for resilience, performance, and durability for the specific application.
