SUNWELL expanded PTFE sheet as similar as GORE, KLINGER, TEADIT,etc.
It is a universal sheet gasket material for most services, seals rough and irregular surfaces.
|
PTFE is featured by the best anti-chemical and dielectric properties among the already known plastics. It is also ageless, nonstick, and able to work from -180 ~ +260 degrees. SUNWELL has three styles of PTFE sheets.
