Uses: Used for tread compound of truck tire and passenger tire, and rubber products requiring high strength and wear resistance, such as high strength conveyor belt and industrial rubber products.

Usage: N115 is one of the smallest particle size, the highest reinforcing and the best wear resistance varieties of carbon black for rubber. When mixing, attention should be paid to uniform dispersion, to prevent excessive heating during mixing and to cause scorch. If necessary, anti-coke agent or other carbon black should be added.

Uses: Used as tread compound for tyres with high strength and low heat generation (including off-road tyres), conveyor belts, seals and other high-quality rubber products.

Usage: The natural rubber of this product has physical and mechanical properties similar to groove black. The rubber of this product has higher tensile strength, tear strength, wear resistance and anti-collapse properties. Compared with other high wear-resistant furnace black, the fixed elongation stress of the rubber is lower, the elongation is higher and the tensile strength is similar. The disadvantage of this product is that it is difficult to disperse in rubber. If it is poorly dispersed, the tensile strength, wear resistance and fatigue property of the compound will be reduced.
