Description
PTFE skived Sheet is manufactured by technique of compacting, sintering, rotary cutting with PTFE granular resin. It has good dielectric performance and non-aging, best anti chemistry corrosion ability and wide applying intension range.
PTFE molded sheet is manufactured by molding process with PTFE regular resin and sintering.
Application
It can be used to make corrosion-resistant liner and gaskets, etc.
