Aflas® Material Description:

Aflas®, or TFE/P rubber, is a fluoropolomer which exhibits excellent chemical, temperature, and steam resistance. Aflas® provides superior performance in water, steam, bases, and virtually all caustics. Aflas® is widely used in the oil exploration and drilling industry due to its excellent steam and H2S resistance.

Aflas® Temperature Range:

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.
