N70M

N70M is a NBR copolymer that provides excellent resistance to petroleum based oils and fuels.

N70M has been developed to offer excellent mechanical properties such as compression set, tear and abrasion resistance, making it ideal for dynamic applications. Good water resistance is also a characteristic of this material.

Meets BS2751 BA70 and ASTM D2000/SAE J200 line call-out M2BG 714, B14, EA14, EF11, EF21, EO14, EO34 and F17.
