ABSTRACT:
Disclosed is an extruded, low density, non-outgassing ehtylenic polymer foam containing 30-85% open cells and the remainder closed cells and having an essentially integral surface. The foam posseses superior compression recovery and lower compression resistance when compared with similarly comprised ehtylenic closed cell foams and superior moisture resistance and handling characteristics when compared to open cell foams.
