N660 carbon black for rubber,It has moderate strengthening properties. It is a soot with high uses. It produces little heat in the tire and is used in all elastomers.
Compared to N550 , it gives even lower heat build up, long fatigue life and good processibility. It is used for body compounds in passenger tires, including innerliners, as well as numerous rubber goods e.g., injection molding.
One of the properties of this soot grade is medium reinforcement, and this grade is used to make the inner layers and outer wall of the tire, cable cover, sealing rings, and so on.Medium reinforcing for inner tubes cable insulation, and body mounts.

Carbon black products manufactured by us are used for tires around the world, in a wide range of rubber products, in pigments, and in other numerous products.
Nature of Carbon Black Reinforcement of Rubber.
Â
Â
N660 carbon black for rubber is mainly used to strengthen rubber in tires, but can also act as a pigment, UV stabilizer, and conductive or insulating agent in a variety of rubber, plastic, ink and coating applications.
Carbon black is a dark black powder used as a pigment in cosmetics such as eyeliner, mascara and lipstick.It is produced by incomplete combustion of carbon-based products such as coal tar,and has been linked to increased incidence of cancer and negative effects on organs.
Carbon black does not dissolve in water, so people are not likely to drink it in contaminated water.
Carbon black particles are heavy and drop quickly out of the air. The dust is a nuisance because it is black and sticky. It's difficult to wipe off skin or other objects. Touching carbon black is not likely to cause serious health effects.
Â
Â
Carbon black can be used in tire and rubber products reinforcement, It is pure black powder or ganular, and has high reinforcement capacity for rubber products and tire manufacture, and could increase rubber service life. Our company could custom produce carbon black products depend on customers requirement.
Furthermore, Crown Chemical has been developing carbon black with various combined functions for special applications.
N660 carbon black for rubber is an important piece in manufacturing rubber tires and other products. Carbon Black are mainly used in various rubber products such as tyres, rubber overshoes, cable, seal ring, tape etc.
