Organotin Catalysts in Cast Elastomer Manufacturing: A Comprehensive Review Abstract: Cast elastomers are crucial materials in various industries, prized for their durability, flexibility, and resistance to wear. Polyurethane (PU) elastomers, a dominant class within cast elastomers, are synthesized through the reaction of polyols and isocyanates. This reaction’s kinetics are often enhanced by catalysts, with organotin...
