It has been found that non-chlorinated pentafluoropropane blowing agents may be used alone or in combination with water in flexible integral skin foams. For example, foams prepared using 1,1,1,3,3-pentafluoropropane (HFA-245fa) 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 many applications including, for example, shoe soles.
