Polyurethane foams made with vegetable oil hydroxylate, polymer polyol and aliphatic polyhydroxy alcohol |
摘要 |
<p>The present invention provides polyurethane foams made from a polyisocyanate and a polyol component containing a polymer polyol (PMPO), a vegetable oil hydroxylate and an aliphatic polyhydroxy alcohol, and optionally a non-vegetable oil-based polyol. The vegetable oil hydroxylates are environmentally-friendly, bio-based polyols. The inclusion of low amounts of a polymer polyol unexpectedly results in a foam having significantly improved tear strength. The combination of polymer polyol and aliphatic polyhydroxy alcohol provides improved foam processing while maintaining or improving tear strength of the foam.</p> |
