NITRILE (SBR) COATED ARAMID FABRIC
Fiber consisting of a long chain polymer containing amines and aromatic components. Infusible, does not melt, does not burn, does not soften. Besides it shows low emission of toxic gases while combustion. Certain aramid can decompose at 500° C, It is thermostable up to 250° C.
NBR, as well known as Acrylonitrile Butadiene 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.
