TFE/P, Aflas®

Common Names:

TFE/P Rubber, FEPM, Aflas®


General Description:

TFE/P Rubber exhibit excellent chemical, heat and steam resistance.  They provide superior performance in water, steam and virtually all caustics making them ideal for pharmaceutical and biotechnology manufacturers that use steam and caustic chemicals in the sterilization process.  TFE/P provides excellent performance in SIP (steam in place), CIP (clean in place) and WFI (water for injection) applications.  TFE/P is widely used in the oil exploration and drilling industry due to its excellent steam and H2S resistance.

Service Temperature:

The temperature ranges presented above are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.
