ABSTRACT:
The present invention relates to a method for making an open celled microcellular foam comprising providing at least one foamable polymer and a crosslinking agent in an extruder, injecting at least one blowing agent into said at least one foamable polymer and said crosslinking agent in said extruder, blending said blowing agent injected into said at least one foamable polymer and said crosslinking agent in said extruder, feeding said blended blowing agent, at least one foamable polymer and said crosslinking agent in said extruder to a die, and depressurizing said blended blowing agent, said at least one foamable polymer and said crosslinking agent.
