FEPM material datasheet


 

● 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
