100% virgin PTFE unsintered tape , PTFE high temperature thread tape
Description:
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.
Applications:
Lining, seaing and oilless lubricating materal and dielectric all any frequencies.
Capacitor dielectric, write isolation, electrical instrument isolation
