Title:
【発明の名称】ポリテトラフルオロエチレン剛性シート材
Document Type and Number:
Japanese Patent JPH09507802
Kind Code:
A
Abstract:
An improved, chemically resistant gasket is constructed from a composite containing outer layers consisting essentially of conformable expanded polytetrafluoroethylene (PTFE) and interior layers consisting essentially of a densified expanded PTFE, wherein the composite layers may optionally contain electrically conductive fillers. The composite is bonded together to form a sheet material that is sufficiently conformable to provide good seal between surfaces and is sufficiently rigid to make the material easy to handle and install. The material of the present invention is particularly suitable for use as a gasket where rigidity is needed, customization or modification of gasket shape is desirable, and/or where a wide, even sealing surface is sought.
