NBR

Materiale con buone caratteristiche meccaniche ed ottima resistenza agli oli minerali e ai grassi. A seconda della quantità di acrilonitrile si possono formulare materiali con buone resistenze alle benzine ed alle basse temperature. Disponiamo di formulazioni arricchite che sono compatibili con ozono.
