NBR Rubber Features:

Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and

vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over

natural rubber.

Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets

as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and

fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.

The flowing is NBR 70 TEST RESPORT
