  • Catalysts for producing polyurethanes
    Patent number: 11680147
    Abstract: A tertiary amine compound is shown and described herein. The tertiary amine is a reaction product of an isocyanate and a compound bearing an active hydrogen and a bicyclic tertiary amine in its molecule. The tertiary amine compounds have been found to be suitable as catalysts for producing polyurethanes. Also shown and described are processes employing the tertiary amine compounds in a reaction of an isocyanate and an alcohol in the presence of the tertiary amine compounds. Further, also shown and described is a method for making the tertiary amine.

  • CATALYSTS FOR THE FORMATION OF POLYURETHANES
    Publication number: 20230134280
    Abstract: The invention relates to novel urethane or carbamate compounds which can act as a catalyst for the reaction of at least one isocyanate compound with at least one isocyanate-reactive compound, in particular for the manufacture of polyisocyanate polyaddition products, such as polyurethanes, in particular, for the manufacture of polyurethane (PU) foams, where they exhibit superior blowing performance.

  • FLEXIBLE FOAMS COMPRISING ADDITIVES FOR IMPROVING HARDNESS
    Publication number: 20230049261
    Abstract: A polyurethane foam-forming composition comprising a polyether functional silicone additive with an active hydrogen atom. The addition of the polyether functional silicone additive to a foam-forming composition for a flexible foam increases the hardness of the resulting foam without adversely affecting other properties of the foam.
