摘要

PROBLEM TO BE SOLVED: To obtain a gasket which has high heat resistance, chemical resistance and creep resistance, excellent sealability and improved moldability.;SOLUTION: The foamed PTFE resin composition comprises a PTFE resin composition composed of 5-65 wt.% of PTFE fibrils and 35-95 wt.% of an inorganic filler in which the PTFE fibrils are mutually entangled or bonded to form three-dimensional network structure and the inorganic filler is approximately uniformly dispersed between the nets of the three-dimensional network structure and has 1.0 specific gravity. The foamed PTFE resin composition is used as a gasket.;COPYRIGHT: (C)2003,JPO
