- FEPM is highly resistant to a wide range of chemicals, such as acid, base and steam.
- FEPM has superior resistance to strong bases in comparison with FKM.
- FEPM finds ever-increasing applications thanks to these unique properties.
- FEPM has much better chemical resistance than FKM and is more cost effective than FFKM. Using AFLAS® will probably mean a significant reduction in your production costs.
- Applications:
- O-rings for Mechanical Seals
- O-rings for Marine Engine
- O-rings for Steam Resistance
- O-rings for downhole Application
- Cable Application
- Transmission Seals for automotive
- Turbo Hose
