1.,Features
 
Corrosion resistance at higher pressures
Offer universal chemical resistance with good temp. range
Excellent release property
Good electrical insulation
Vapour resistance
 
 
2.Product introduction

PTFE is one of the best corrosion resistance materials.
Rubber and PTFE have many of the same characteristics, different characteristics of rubber is different , such as, NBR rubber oil resistant performance is good, butyl rubber( IIR) tightness is good, EPDM rubber heat resistance, ozone resistance is superior, the silicone rubber heat-resistant hardy superior performance, FKM rubber high temperature resistant performance is very good. Common characteristic are good rubber elasticity, good sealed performance, and defect is easy ageing.
 
3.Advantages

1)High temperature resistance, working temperature can reach 250 °C.
2)Good low temperature resistance, good mechanical toughness; Even if the temperature dropped to - 196 °C, it can also maintain the elongation of 5%.
3) Corrosion resistance- to most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents.
4)Weather-proof, service life is longest.
5) High lubrication - the lowest friction coefficient in solid materials.
6)Inadhesion - the surface tension of the solid material is is the smallest, don't adhere to any material.
7)Non-toxic, has a physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.
