Tetrafluoroethylene Propylene (FEPM, AFLAS®) Materials
Providing Superior All-Around Chemical Resistance
Tetrafluoroethylene propylene—more commonly known as FEPM or the tradename AFLAS®—is a partially fluorinated polymer made of propylene and tetrafluoroethylene. This material is a melt-processable rubber, meaning it can be used by conventional injection molding and extrusion equipment. Tetrafluoroethylene propylene offers the following advantages over other rubber materials for the production of seals:
- Excellent heat resistance
- Unparalleled chemical resistance
- High electrical resistance
If you are manufacturing seals in harsh environments, consider putting tetrafluoroethylene propylene to work for your application. Reach out to North Coast Seal to learn more.
The Benefits of Tetrafluoroethylene Propylene
Exceptional Heat and Chemical Resistance for Sealing Applications
Tetrafluoroethylene propylene is known as offering among the highest capabilities for chemical resistance. The material is heat resistant up to approximately 450°F (232°C) and is cold flexible down to approximately 15°F (-9°C).
Tetrafluoroethylene propylene is compatible with the following:
- Bases
- Phosphate esters
- Amines
- Engine oils
- Steam
- Hot water
- Pulp and paper liquors
The material is not compatible with aromatic fuels, ketones, and chlorinated hydrocarbons.
