Abstract
A three dimensional porous elastomeric polymeric material is described that has a morphology primarily of polymeric fibers fused randomly along portions of their length, with a cross-section of a network of irregular polymeric areas that are interconnected to define interconnected voids; where the bulk density of the material is at least 0.35 grams/cc. The material is useful in garment and other protective covering applications where it can be adhered to various substrates to provide improved abrasion resistance. Composites of the material are described also.
