Polytetrafluoroethylene(PTFE) skived sheet tape & film

¡¡¡¡¡¡¡¡

1¡¢Feature£ºPTFE resin is first moulded into worj-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.

2¡¢Usage £ºLining,seaing and oilless lubricating material and dielectric at any frequencies.Capacitor dielectric, wire isolation,electrical instrument isolation.
