  • Bioresin composition for use in forming a rigid polyurethane foam article
    Patent number: 8784680
    Abstract: A bioresin composition is used to form a rigid polyurethane article that includes a first and a second biopolyol and is substantially free of aprotic solvents that chemically decompose in the presence of water. The first biopolyol includes a natural oil component. The second biopolyol includes the reaction product of a natural carbohydrate and an alkylene oxide. The rigid polyurethane foam article includes the reaction product of the bioresin composition and an isocyanate which are reacted in the presence of a chemical blowing agent.
    Type: Grant
