Teflon Dichtringe

Teflon Sealing gaskets (Teflon EnvelopGasket)are type of static seal. It is composed of elastic materials such as compressed non-asbestos sheet and a PPTFE has superior properties against chemical (not affected by all chemicals except molten alkali metal and fluorine at elevated temperature) and a wide working temperature range. (from -180 260) the coefficient of static and dynamic friction of PTFE are very low. PTFE is the best of the non-stick materials. It has excellent weathering and aging characteristics. Application areas: PTFE envelope gasket is used to seal pipe flanges glass lined, PVC or FRP. Low bolt torque effecting a seal and chemical compatibility is a main characteristic of this type of gasket.
