Patent ID: 6875814

Claim:
An extrudable composition for passing through a die, said composition comprising: A) a non-fluorinated melt processable polymer, wherein said non-fluorinated melt processable polymer is a hydrocarbon resin selected from the group consisting of i) polyethylenes, ii) polypropylene, iii) polybutene-1, iv) poly(3-methylbutene), v) poly(methylpentene), and vi) copolymers of ethylene with an alpha-olefin; and B) 25 to 2000 parts per million by weight, based on total weight of the extrudable composition, of fluoropolymer, said fluoropolymer having a weight average particle size greater than 2 microns and less than 10 microns, as measured at a point immediately preceding the die; and wherein said composition is substantially free of interfacial agent.
