Patent ID: 8141717

Claim:
A composition comprising: a sintered porous polymeric material comprising a sintered mixture of particles of at least one plastic and particles of at least one thermoplastic elastomer, the sintered porous polymeric material having a porosity ranging from 20% to 80% and a rigidity of less than 5 pounds, wherein the at least one plastic is selected from the group consisting of polyethylene, polypropylene, polyesters, polycarbonates, polyvinylidene fluoride, polytetrafluoroethylene, polyethersulfones, polystyrenes, polyether imides, polyetheretherketones, and polysulfones and combinations thereof, and wherein the at least one thermoplastic elastomer is selected from the group consisting of thermoplastic polyurethanes, polyisobutylene, polybutenes, polyethylene-propylene copolymer, polyethylene-butene copolymer, polyethylene-octene copolymer, polyethylene-hexene copolymer, chlorinated polyethylene, chloro-sulfonated polyethylene, styrene-ethylene-butadiene-styrene and 1,3-dienes and combinations thereof.
