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