It belongs to the family of synthetic rubbers, it is a copolymer of butadiene and acrylonitrile, highly resistant to oils and hydrocarbons.

It is used in the automotive and aircraft industries for fuel hydrocarbon handling hoses and hydrocarbon handling hoses, seals and washers, in the nuclear industry to make protective gloves, it is used to create molded products, adhesives, sealants, sponges, expandable foams and rubber mats floor.

Medium resistance to low temperatures and weathering.

Low resistance against aromatic hydrocarbons (benzene, toluene, xylene).

Good adhesion to steel.

Very good resistance to oils and aliphatic hydrocarbons (hexane, heptane, methane, ethane, octane, butane, pentane).

Good resistance to acids (except oxidants), fatty acids, vegetable or animal fats.

Its low permeability to air and other hydrocarbon gases such as natural gas, propane and butane is noteworthy.

Hardnesses from 50ºshA to 70ºshA, normally black, although there are varieties in green and gray (on request in minimum quantities).
