Document Type and Number:
Japanese Patent JPH01225645
Kind Code:
A
Abstract:
PURPOSE: To obtain the title composite material having a desired permittivity, excellent heat resistance, chemical resistance, nonbrittleness and flexibility and suited for an insulation material etc., by adding a ground heat-meltable fluorocarbon resin foam to a polymeric material.
CONSTITUTION: A given amount of heat-meltable fluorocarbon resin particles in the form of hollow particles containing air in their insides, formed by mechanically grinding a foam of a heat-meltable fluorocarbon resin such as a tetrafluoroethylene/perfluoroalkyl vinyl ether of an expansion ratio of, e.g., about 60%, are added to a polymeric material such as a tetrafluoroethylene resin.
