ABSTRACT:
The invention relates to polymer blends which can be used both in foamed and unfoamed states as a replacement for conventional EPDM and other elastomers. The composition of the blend includes a single-site catalyzed polyolefin resin having a density of below 0.878 g cm.sup.-3 and up to 40 weight percent a polyolefin including ethylene and propylene. The polymer blend is cross-linked. The polymer blends are formable and foamable. The use of sulfur to vulcanize the polymer blend is not necessary. The polymer blends can be used to make foam for floatation or for making gaskets.
