First Claim
Patent Images
1. A process for producing a polymeric foam comprising the following steps:
- a. providing a foamable polymer composition comprising a blowing agent dispersed in a polymer matrix, the polymer matrix having a softening temperature; and
b. exposing the foamable polymer composition while at a temperature at or above the softening temperature of the polymer matrix to an environment having a pressure low enough to cause the foamable polymer composition to expand into a polymeric foam;
wherein the foamable polymer composition further comprises alumina boehmite dispersed in the polymer matrix.
