Carbon black is an amorphous carbon, light, loose and very fine black powder with good dispersibility, high tinting strength and low viscosity. Suitable for all kinds of rubber. Carbon black has high structure, fine particles and easy to disperse in the rubber compound. The vulcanized rubber has high tensile strength, tear strength and tensile stress, small deformation, low heat generation, high elasticity and high yield strength. Good performance, mainly used in tires, sealing strips, inner tubes, hoses, tapes, cables, shoes, coils, model products, etc.
