PTFE moulded sheet
teflon PTFE moulded sheet for lining bearing pads seals and electrical insulation
Features:
PTFE resin is first molded into work-blank and then skived. The PTFE resin skived sheet & tape are highly dielectric. Chemical resistant and not aging. They have a wide range of operation temperature.
