Urethane is a high-performance engineered elastomer.  It offers superior characteristics for high demand applications.  Urethane is known for its excellent properties of abrasion resistance, cut and tear strength, load bearing, shock absorption and chemical and environmental resistance.

In addition to being a top choice in demanding applications, urethane has other characteristics that make it a viable option in a variety of non-traditional applications.  It is available in a wide range of hardnesses from very soft, like a rubber band, to very hard like a bowling ball, and in several different colors.  Because All-State molds the parts in-house, simple to complex designs can be accommodated.  Urethane can be directly molded to many different materials including steel, aluminum and plastic to enhance performance characteristics.
