Product Description

NBR Rubber Sheet

Nitrile 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 sheet 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, and has satisfactory resistance to general hydrocarbons
