TFE/P Aflas® (FEPM)

TFE/P is a copolymer of tetrafluoroethylene and propylene with a fluorine content of app. 54%. This material is unique due to its resistance to petroleum products, steam, and phosphate-esters. In some respects it exhibits media compatibility properties similar to ethylene propylene and fluorocarbon. The compression set resistance at high temperatures is inferior to standard fluorocarbons. Service temperatures are -5°C (25°F) to +204°C (+400°F).

TFE/P provides improved chemical resistance to a wide spectrum of automotive fluids and additives. It is resistant to engine oils of all types, engine coolants with high level of rust inhibitors, extreme pressure (EP) gear lubricants, transmission and power steering fluids, and all types of brake fluids including DOT 3, mineral oil, and silicone oil.

TFE/P is ideal for heat transfer media, amines, acids and bases, as well as hot water and steam up to +170°C (+340°F).
