Latest Patents

Laxmi C Gupta holds 1 patent for her invention titled "Heat-stabilized polyurethane elastomer." This patent describes a method for heat stabilization of polyurethane elastomer catalyzed with an organo-metallic catalyst. The process involves adding a minor amount of elemental sulfur or sulfur-donor material to the liquid mixture of polyol and organic polyisocyanate at the time the catalyst is introduced. The sulfur remains inert during the polymerization reaction, ensuring that the cured elastomer maintains its integrity at temperatures not exceeding approximately 200°F. When the temperature exceeds this threshold, the sulfur reacts with the catalyst to form a metallic sulfide, effectively neutralizing the catalyst. This innovation prevents the depolymerization of the urethane, allowing it to remain solid at high temperatures for extended periods.
