The base material used by SuperPro is a polyurethane elastomer; a class of Thermosetting synthetic polymer that involves the reaction of various types of isocyanate resins with curing agents, to give an extremely durable material with the best features of rubber and plastic. Since the introduction of polyurethane into the aftermarket suspension industry in the early 80s many have tried but few have succeeded in manufacturing accurate, durable parts consistently. Anyone can take two tins and mix part A with part B and get a result. It takes foresight in management and a strong integration with technology to achieve a result every time, which is what SuperPro prides itself on.
