short description:


Product Detail

Product Tags

Compared to general fluoro rubber, Aflas FEPM has better resistance to alkali and acid. Better electrical insulation and impermeability.

● Hardness: 75 Shore A

● Color: Black, brown

● Application: make O-rings, irregular-shaped rings, gaskets

● Advantage: better resistance to alkali and acid. Better electrical insulation and impermeability.

● Disadvantage: processing is difficult
