คำอธิบายสินค้า

Product name
PTFE rotary shaft seals for valve and pump
 

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
