Abstract
A composition for forming polyurethane foams is provided using epoxidized triglycerides with unopened rings. The composition further includes a polyol, a blowing agent, and a catalyst that catalyzes the reaction of polyols with isocyanates to form polyurethanes. The polyol is a polyoxyalklylene and the epoxidized triglyceride is an epoxidized soybean oil. A method for forming polyurethane foam using the aforementioned composition is also provided.
Claims17
A composition for forming polyurethane foams, the composition comprising:
- a polyol;
- an epoxidized triglyceride with unopened epoxide rings wherein at least 95% of epoxide rings on the epoxidized triglyceride with unopened epoxide rings are unopened and the weight ratio of the epoxidized triglyceride with unopened epoxide rings are to the polyol is less than 0.5 and wherein the epoxidized triglyceride with unopened epoxide rings is present in an amount from about 2 to 10 weight percent of the total weight of the composition for forming polyurethane foams, the epoxidized triglyceride with unopened epoxide rings including an epoxidized linoleum having formula I:
- a blowing agent;
- and
- a catalyst that catalyzes reaction of polyols with isocyanates to form polyurethanes.
A method for forming polyurethane foams in a molding apparatus, the method comprising:
- directing a polyol composition into a mold, the polyol composition including a mixture of an epoxidized triglyceride with unopened rings, a polyol, a blowing agent and a catalyst, wherein at least 95% of epoxide rings on the epoxidized triglyceride with unopened epoxide rings are unopened and the weight ratio of the epoxidized triglyceride with unopened epoxide rings are to the polyol is less than 0.5 and wherein the epoxidized triglyceride with unopened epoxide rings are is present in an amount from about 2 to 10 weight percent of the total weight of the composition for forming polyurethane foams, the epoxidized triglyceride with unopened epoxide rings including an epoxidized linoleum having formula I:
- and
- directing an isocyanate composition into the mold to form a foamed polyurethane.
