Material Data Sheet
AFLAS* AF101- black (bisphenol cross linked)

General

AF101-B85 is a Tetrafluorethylene/Propylene copolymer (TFE/P), commonly referred to as FEPM or AFLAS*. AFLAS* has a very high resistance to hydraulic fluids ( incl. Alkyl-Acryl-Phosphate Esters), all break fluids (on glycol, mineral and silicone base), acids, steam and hot water, sour, oils/gases (H2S) and heavily formulated oils with amine additives.

Main application

Static and dynamic seals (standard and special) wipers, O-rings , flange seals, rotary seals, rubber energizer (preload elements). Applications where high temp and/or chemical resistance is required, oil and gas industry.

Analysis and Evaluation

The mentioned properties are only valid for test pieces of the corresponding ISO, DIN and ASTM standards. They cannot be directly related to seals, gasket and other sealing products and should be used only as a general guide.
