Product Description

Nitrile Rubber Gaskets

Nitrile rubber, as well known as Butadiene Acrilonitrile, Buna-N, Perbunan, or NBR rubber, was first developed in 1941 in a project meant to

find an oil resistant rubber. However, NBR’s oil resistance depends on the grade of acrylonitrile

The higher the grade of acrylonitrile the better is resistance to oil and fuel. However, as the grade of acrylonitrile increases, the endurance

to low temperatures decreases. NBR has good abrasion resistance nonetheless its physical properties are moderate in comparison with

the Natural Rubber.

Nitrile rubber gasket has outstanding resistance to: oils, petrols, solvents, and lubricants, but poor ozone resistance. Poor ozone resistance.

Good resistance to inorganic chemical products except antioxidant agents and chlorine, it has satisfactory resistance to general hydrocarbons

Advantages

• Good general resistance to solvents, lubricants

• Good general resistance to oils, petrols

• Good compression set, tear strength

• Wide range of sevice temperature

• Good resistance to alkalis acids

• Good tensile strength, flexibility

• Moderate aging properties

• Good adhesion to metal.

• Good use with water

• Has good recovery
