Arizona Sealing Devices, Inc. Compound Designation: Aflas
Standard Color: Black
Description: A copolymer of tetrafluoroethylene/ propylene, TFE/P can offer a combination of high temperature and chemical resistance.
- Seals for oil field, aerospace, chemical and general industrial environments.
Temperature Range: Standard Compound: -14° to +446°F.
Hardness (Shore A): 60 to 90.
Features: Resistance to a wide range of chemicals, high temperature and electrical capabilities give broad application diversity. TFE/P has resistance to acids, bases steam/hot water, corrosion inhibitors, oils and lubricants, and industrial solvents. TFE/P also offer improved low temperature properties over most fluoroelastomers.
Limitations: Tests have shown that other FKM elastomers are recommended for automotive fuels since they have less volume swell than TFE/P. Also, TFE/P has shown to have less than desirable results when exposed to toluene, ethers, ketones, and acetic acid.
