  • Integral skin foams employing 1,1,1,3,3-pentafluoropropane as blowing agent
    Publication number: 20030225177
    Abstract: The invention relates to integral skin foams and in particular to integral skin foams that are prepared using 1,1,1,3,3-pentafluoropropane (HFA-245fa) alone or in combination with water as the blowing agent. The foams 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.
