N220: I t has low particle diameter ,good reinforcing property,good wear resistance;smooth surface,low heat production,high surface activity;
N234: 10% higher wear resistance than N220, good wear resistance.Mainly used in high-speed tire tread and rubber products;
N326: has fairly high tensile strength,tear strength and wear resistance. It is mainly used in tire tread requiring high strength and low heat production.
N330: Good reinforcing property to rubbers,more mileage than normal or low-structure carbon black;high heat production.Used in tire sidewall.
N339: Its reinforcing property,wear resistance is near to those of N220;especially suitable for the Styrene-Butadiene Rubber and cis-1,4-Polybutadiene rubber system.
N375: Similar to N339,but has slightly lower heat production.Mainlu used in the tire tread of saloon sedan etc.
N550: It’s a high-structured carbon black, used in the tire body and tire sidewalls.
N660: Average particle diameter is 49-60, strong cohesive force,good flex fatigue resistance,good processability;It has fairly high tensile strength,high elasticity and low heat production. It is suitable for the tire sidewalls,tube tyre,buffer layer tire etc. also used in non-tire rubber,such as pigments,printing ink,paper and plastics etc.
N115:the use and role of the N115 carbon black in rubber particle size is the smallest,highest reinforcement,wear one of the best varieties,mixing should pay attention dispersed,when the temperature is too high to prevent the mixing caused scorch,necessary,to add anti-coke agents or with other carbon black.
N121:the products are generally reinforcing properties and dispersion in rubber compound and the N220 rather,the wear resistance of rubber is better than N220.in the N110 series carbon black ,the good performance of the product procession.
