Products Description
The reinforcing properties, wear resistance and crack resistance of this product in the tread compound are close to N220 carbon black, and the extrusion performance is also good, especially suitable for the combined system of styrene butadiene rubber / butadiene rubber. The carbon pigment here refers to carbon black N339.
Product application
Because of its excellent wear resistance and crack growth resistance, N339 carbon black is especially suitable for rubber products requiring high wear resistance, such as tread adhesives for passenger tires and truck tires. N330 carbon black is widely used in many parts of tires and other rubber industrial products because of its good reinforcing properties and elasticity. The carbon pigment here refers to carbon black N339.
N330 and N339 are different types of carbon black. From the appearance of the two, it is difficult to see the difference with the naked eye (both are black), but there is a big difference in their physical properties. In terms of wear resistance, N2339 is about 10% higher than N330. N339 carbon black, high wear resistance and crack resistance, wear resistance is 20%-30% higher than N330, can give rubber particles high tensile strength and tear strength, and has a certain conductivity reinforcement type carbon black, used in tire tread, high quality industrial rubber products and high load transport belt. The carbon pigment here refers to carbon black N339. The blackness is higher than that of other varieties, and it is widely used in plastic masterbatches and leather paper mills as printing and dyeing raw materials. N339 has a theoretical particle size of 22nm, excellent wear resistance, high dynamic stability and low rebound rate. High performance car tread, high quality industrial rubber products high load conveyor belt. Rubber carbon black N339, made for tires and high wear resistance rubber products. The carbon pigment here refers to carbon black N339.
