| 发明名称 | Bioresin composition for use in forming a rigid polyurethane foam article | ||
| 摘要 | 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. | ||

| 主权项 | 1. A bioresin composition substantially free of aprotic solvents that chemically decompose in the presence of water, said bioresin composition comprising: (A) a first biopolyol comprising a natural oil component, said first biopolyol having: (a) a nominal functionality of at least 2.5,(b) a hydroxyl number of from about 375 to about 575 mg KOH/g, and(c) a viscosity of from about 500 cps to about 1500 cps at 77° F., (B) a second biopolyol comprising the reaction product of a natural carbohydrate and an alkylene oxide,wherein said second biopolyol and said first biopolyol are present in a weight ratio of greater than 1:1 to about 3:1, and (C) an aprotic solvent that does not chemically decompose in the presence of water. | ||
