Patent ID: 7557154

Claim:
A polymer composition comprising a combination of: a matrix polymer component; a fluoropolymer, wherein the fluoropolymer is encapsulated by an encapsulating polymer comprising a styrene-acrylonitrile copolymer, an acrylonitrile-butadiene-styrene copolymer, alpha-alkyl-styrene-acrylonitrile copolymer, an alpha-methylstyrene-acrylonitrile copolymer, a styrene-butadiene rubber, or a combination comprising at least one of the foregoing polymers; and a filler, wherein the polymer composition has a tensile modulus of greater than or equal to about 3 GPa, and a nominal elongation at break of greater than or equal to about 20%, measured in accordance with ISO-527, using a rate of pull of 1 mm/minute followed by 5 mm/minute.
