Polytetrafluoroethylene(PTFE) Tape&Film
Characteristic
of the products
PTFE resin is
first moulded into work-blank and then skived.The PTFE resin skived sheet&tape
are highly dielectric.Chemical resistant and not aging.They have
a wide tange of operation temperature.
Polytetrafluoroethylene(PTFE) membrane have
tensile strength good,
fine characteristics, such as viscidity,etc.
high,
insulating.
Use of the
products
Lining,sealing and lubricating material and dielectric at any
frequencies.Wire insulation,electricalinstrument insulation.
