Isocyanate-Functional Polymer Components and Polyurethane Articles Formed From Recycled Polyurethane Articles and Associated Methods for Forming Same - A simplified explanation of the abstract
This abstract first appeared for US patent application 18748720 titled 'Isocyanate-Functional Polymer Components and Polyurethane Articles Formed From Recycled Polyurethane Articles and Associated Methods for Forming Same
Simplified Explanation: The patent application describes a method of forming an isocyanate-functional polymer component using recycled polyurethane and isocyanate components, which can be used to create polyurethane or polyurethane foam articles.
- Recycled polyurethane and a first isocyanate component are mixed to form a first mixture.
- The mixture is heated to transform the recycled polyurethane into a liquid form and react it with the isocyanate component.
- The resulting polymer component has an isocyanate-functional group content greater than zero but less than the isocyanate component.
- The polymer component can be used to create polyurethane or polyurethane foam articles by reacting it with a second isocyanate component and an isocyanate-reactive component.
Key Features and Innovation:
- Recycling of polyurethane materials for sustainable production.
- Transformation of recycled polyurethane into a liquid form for reactivity.
- Controlled isocyanate-functional group content in the polymer component.

Original Abstract Submitted
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.
