Adiprene® L 83

About
ADIPRENE L 83 urethane rubber is one of a series of polyether-based liquid urethane prepolymers which can be cured to a strong, rubbery solid by the reaction of the isocyanate groups with polyamine compounds. When cured with MBCA 1 urethane curative, ADIPRENE L 83 yields vulcanizates in the 80-85 durometer A hardness range. ADIPRENE L 83 can be cast, compression molded, sprayed or spread to produce a wide variety of mechanical goods and protective and decorative coatings. Vulcanizates of ADIPRENE L 83 provide a unique combination of properties including excellent abrasion resistance, resilience, hydrolytic stability and overall mechanical properties-which make it especially suitable for handling abrasive slurries from mine and mill operations. Vulcanizates of ADIPRENE L 83 cured with MBCA have been used successfuly in the mining industry to line slurry pumps, agitators, flotation rotors and stators, cyclone separator systems, piping, valves and screens, and in the recreational market for roller skate and skateboard wheels.&&
