- Description
- A copolymer of tetrafluoroethylene/propylene, TFE/P can offer a combination of high temperature and chemical resistance.
- Key Use
- Seals for oil field, aerospace, chemical and general industrial environments.
- Temperature Range
- Standard Compound: +14°F to +446°F
- Hardness (Shore A)
- 60 to 90
- Features
-
- Resistance to a wide range of chemicals, high temperatures and electrical capabilities give broad application diversity.
- TFE/P have resistance to acids and 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.
- TFE/P has shown to have less than desirable results when exposed to toluene, ethers, ketones and acetic acid.
