Physical & Chemical Properties: It is a derived variety of carbon black N550. The structure is lower than N550. With medium-performance reinforcement, it is a general purpose furnace black.

Application: Mainly used in tread tires, particularly suitable for the natural rubber-based buffer layer rubber. It can also be used in tire base rubber, tape covering rubber, other rubber products, wire and cable sheathing compound.

Function: Its rubber mass is press out smooth surface, small mouth expansion, high tensile strength and elongation of the vulcanizates. Compared with carbon black N550, the tensile stress compared is lower, the flexibility and resistance to fatigue is better.
