Semi-rigid polyurethane foams from a mixture of oxypropylated polyols |
| abstract |
SEMI-RIGID POLYURETHANE FOAM COMPOSITIONS ARE PROVIDED WHICH HAVE EXCELLENT ENERGY ABSORPTION AND LOW REBOUND PROPERTIES WHILE RETAINING OTHER DESIRABLE PHYSICAL PROPERTIES CHARACTERISTIC OF SEMI-RIGID POLYURETHANE FOAMS THE POLURETHANE FOAMS MAY BE PREPARED BY REACTING AN AN ORGANC POLYISOCYANATE WITH A POLYOXYPROPYLENE ETHER OF 2,2-BIS(4-HYDROXYPHENYL) PROPANE AND A POLYOXYPROPYLENE ETHER OF SORBITOL. ALSO PROVIDED ARE POLYOL COMPOSITIONS SUITABLE FOR THE PREPARATION OF CELLULAR POLYURETHANES WHICH COMPRISE A POLYOXYPROPYLENE ETHER OF 2,2-BIS(4-HYDROXYPHENYL) PROPANE WHEREIN THE ETHER CONTAINS FROM 4 TO 9 MOLS OF OXPYROPYLENE OER MOL OF ETHER AND A POLYOXYPROPYLENE ETHER OF SORBITOL CONTAINING FROM 30 TO 55 MOLS OF OXYPROPYLENE PER MOL OF ETHER. |
