N550: This product is easily dispersed, can be given to rubber very high, the pressure fast, smooth surface pressure, high temperature properties of vulcanized rubber and good thermal conductivity properties, reinforcing the performance, flexibility and resilience are better
N660: this applies to all kinds of rubber products, and semi-reinforcing furnace black, of the goods have a high structure and smaller particles, easily dispersed in rubber, rubber vulcanization of tensile strength, tear strength and stretch will be High stress, deformation and smaller, low-heat, flexible and flex-resistant Qu good.
N772: for the tire carcass and molded products
N774: the use of the N774 carbon black rubber process better performance, the amount of filler can also be very high, the vulcanization of rubber flexible, low-heat, good dynamic performance
