n115 is mainly used for cross-country tire and truck tire tread. this product is the rubber with carbon black particle size of the smallest, reinforcing the best, one of the best varieties of wear-resisting performance, but high energy consumption of the mixing, dispersion is difficult, rolling and extrusion is not easy, so applications should be restricted.

n220 are suitable for all kinds of rubber, high wear resistance than n330 10% - 20%, can has high tensile strength and tear strength, and has a certain electrical conductivity. it is mainly used for truck tyres, passenger tire tread rubber, and require high strength, high wear-resisting rubber products.

n234 abrasion resistance about 10% higher than n220, use under high severity, more can show good wear-resisting performance. mainly used for high speed tire surface glue and high quality rubber products.

n326 in natural rubber with high tensile strength, tear strength, abrasion resistance and resistance to cracking up. mainly used for requirement of high strength and low heat generating tires (including cross-country tire tread rubber, applies to the conveyor belt, sealing products and other high quality rubber industry products.

n330 is a kind of carbon black with better reinforcing, it gives better strong stretching intensity, resisting avulsion intensity, abrasion resistance and flexibility. mainly used in tire surface, shade cloth glue, the tire and all kinds of rubber industry products.

n339 in tread rubber reinforcing properties, wear resistance and crack growth resistance to n220 carbon black, especially suitable for styrene butadiene rubber and butadiene rubber and system. mainly used in passenger tire, truck tire tread rubber, conveyer belt, rubber hose and various require high wear resistance of rubber industry products.

n375 and n339 performance basic same, heat generating a little lower than n339. mainly used in car tyres, truck tyres and cross-country tire tread rubber.

n550 suitable and various synthetic rubber, natural rubber and can give higher stiffness, rubber extrusion speed, small mouth expansion, a smooth surface. thermal conductivity is good, high temperature performance of vulcanized rubber and reinforcing properties, elasticity and resilience is better. mainly used in tire cord rubber, tire, inner tube, and extrusion, calendering products of rubber.

n539 rubber used in this product, its pressure out of the surface is smooth, small mouth expansion. vulcanizates higher tensile strength and elongation, stretching stress was lower than those of n550, elasticity and fatigue resistance are good. mainly used in tire rubber body, especially applicable to give priority to with natural rubber buffer layer rubber, can be used for base rubber tires, tape and other rubber products, wire and cable sheath material.

n660 this product is suitable for all kinds of rubber, compared with half a reinforcing carbon black with high structure, fine particles, easy disperse in rubber, and analysis of the tensile strength, tear strength and stretch stress is higher, and the deformation is small, low heating, good elasticity and flexor interference resistance. mainly used in tire wheel curtain fabric, inner tube, cycling, rubber hose, adhesive tape, cable, shoes and rolled products, model products, etc.

n762 reinforcing carbon black is produced by new technology of gas thermal cracking method, its characteristic is to a large number of filling, rubber processing performance is good. the carbon black with rubber high elongation, low heat, high flexibility and good resistance to aging performance, increase liquidity rubber processing, improve the adhesive effect of products and other materials, and improve the appearance quality of products. mainly used for natural rubber, neoprene, nitrile butadiene rubber products, both reinforcing and filling effect.

n774 this product is suitable for all kinds of rubber. this product has good wear resistance, tear resistance, heat resistance, cold resistant, oil resistant. belong to the low pollution on semi reinforcing carbon black. its characteristic is can be a lot of filling, rubber processing performance is good. the carbon black with rubber high elongation, low heat, high flexibility and good resistance to aging performance, increase liquidity rubber processing, improve the adhesive effect of products and other materials, and improve the appearance quality of products. used in tires with beam or cord fabric layer, inner tube, tire, rubber hose, adhesive tape, cable, shoes and rolled products, model products, natural rubber, neoprene, nitrile butadiene rubber products, both reinforcing and filling effect.
