  • Patent number: 12054589
    Abstract: A method of forming an isocyanate-functional polymer component includes forming a first mixture by mixing a recycled polyurethane article and a first isocyanate component having isocyanate-functional groups. The first mixture is heated to a temperature sufficient to transform the recycled polyurethane article from a solid form to a liquid form and react the liquid recycled polyurethane component with the first isocyanate component to form an isocyanate-functional polymer component having an isocyanate-functional group content greater than zero and less than isocyanate-functional group content of the first isocyanate component. The formed isocyanate-functional polymer component may then be used for forming a polyurethane article or polyurethane foam article that is the reaction product of the formed isocyanate-functional polymer component, a second isocyanate component and an isocyanate-reactive component having hydroxyl-functional groups.

  • Publication number: 20070191538
    Abstract: A resin composition includes a compound having at least two reactive hydrogen atoms and a polyurethane encapsulated particle including a core particle and a polyurethane layer disposed about the core particle. The resin composition may be used in an article and in a method of making the article. The article includes the reaction product of the resin composition and an isocyanate that are reacted in the presence of the polyurethane encapsulated particle. The method of making the article includes providing the core particle in a vessel. The method also includes introducing and combining a polyol component and an isocyanate component to encapsulate the core particle. The method further includes introducing and combining the resin composition and the isocyanate, in the presence of the polyurethane encapsulated particle, to form the article.
