Standard Specification for Flexible Cellular Materials Made From Polyolefin Plastics
This specification applies to flexible closed-cell materials made from polyolefin plastics and blends of polyolefin plastics.
Two types of flexible, closed-cell polyolefin foams are covered: * type I – closed cell foams made with polyolefin plastics and either chemically or radiation crosslinked, and * type II – closed cell foams made with polyolefin plastics that are non-crosslinked.
Cellular polyolefin foams furnished under this specification shall be manufactured from any resin or blend of resins that are members of the polyolefin family together with added compounding materials. Unless otherwise specified, the color of cellular polyolefin foams shall be natural.
In this standard, tensile test is done according to ASTM D412, tear test is done according to ASTM D624
