NITRILE (NBR) COATED ARAMID TIRE CORD
Tire cord fabric is a type of industrial fabric which is constructed using High Tenacity yarns in the warp direction and yarns of negligible resistance in weft direction which is used to hold warn yarns locked in their position. Tire cord coated fabrics provides fundamental properties such as controlled deformation, high strength, abrasion resistance, etc. Widely used by the tire industry, it is also employed for the rubber hose manufacture, air springs, expansion joints, among many other applications.
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.
