Product name
Mixed RPTFE O-ring for Mechanical Sealing
The superior dielectric properties especially at high radar and microwave frequencies makes PTFE widely use as an insulation material. PTFE is also works in a wide temperature from -180°C to +260°C.
PTFE is capable of much higher temperatures than many other materials.It is classed as a high performance substitute over weaker and lower melting point polyethylene.
Main properties
. Excellent corrosion resistance
. Good electrical insulation performance
. High temperaturer resistance
. low coefficient of friction
. Good non-sticky properties
Application
PTFE is widely used in chemical anti-corrosion, mechanical seal,engineering piping, electrical insulation,pump&valve
fluid,aviation,textile,ceramic and other industries
