Corrosion resistance stainless steel flexible metallic ptfe lined bellow expansion joint
Characteristic of PTFE metal expansion joint
1. Polytetrafluoroethylene theoretical temperature is -200 to 260 degrees Celsius, the actual recommended temperature is -170 to 230 degrees Celsius.
2. Polytetrafluoroethylene has a very small surface length and wetting angle, so it has a non sticky surface.
