ABSTRACT:
It has been found that 1,1,1,2-tetrafluoroethane (HFC-134a) may be used alone or in combination with water as blowing agents in flexible integral skin foams. Foams prepared using HFC-134a alone or in combination with water exhibit physical characteristics such as resistance to abrasion and cracking on flex comparable to conventional chlorinated fluorocarbon blown foams. The foams of the present invention are suitable for use in shoe sole applications.
