Tetrapropylene fluororubber (AFLAS) is a copolymer of tetrafluoroethylene and propylene through lotion polymerization. It has excellent high-temperature aging resistance, acid and alkali resistance, weather aging resistance, excellent high-temperature water vapor resistance, and unique compression permanent deformation resistance. Except for its inferior fuel resistance to Type 26 fluororubber, tetrapropylene fluororubber has considerable resistance to lubricating oil, hydraulic oil, engine oil, and brake fluid. The biggest drawback of tetrafluoroethylene rubber is its poor cold resistance.
