Rubber PTFE ,Teflon expansion joint

PTFE, PE, rubber characteristics introduction

PTFEis one of the best corrosion resistance materials.


PE:is a kind of thermoplastic by polymerization of vinyl resin. Has good low temperature resistance (the lowest temperature can reach 70 ~ 100°C), chemical stability is good, most of acid and alkali erosion (acid) with characteristics of oxidation resistance, temperature does not dissolve in solvents, small water imbibition, excellent electrical insulation properties; But polyethylene for environmental stress (chemical and mechanical effect) is very sensitive, heat aging resistance is poor.


Rubberand 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.
