Product Description

Carbon Black

Carbon black is mainly composed of carbon monomers, and contains a small amount of oxygen, hydrogen and sulfur and other elements. Carbon black particles are nearly spherical, with a particle size between 10 and 500μm. Many particles are often fused or agglomerated into three-dimensional bonded dendritic or fibrous aggregates. In rubber processing, it is added to rubber through compounding as a reinforcing agent (see reinforcing materials) and as a filler.
Carbon black is often categorized with respect to its production method, such as bath black, furnace black, and thermally cracked black. They can also be classified according to their use, such as carbon black for rubber and carbon black for pigmentation. The naming principle of carbon black varieties is gradually formed in the process of production and use.

Application

Carbon black is mainly used as a reinforcing agent for rubber, filler and in tire manufacturing. In addition, it is also used as a coloring agent for inks, coatings and plastics, and as a UV shielding agent for plastic products. It is also an important additive in many other products such as electrodes, dry cell batteries, resistors, explosives, cosmetics and polishing creams.
Carbon black is mainly used in rubber products. The finer the particle size of carbon black, the more superior its reinforcing properties; the higher the structural degree of carbon black, the higher its constant tensile stress and modulus. Fine particle size reinforcing varieties are mainly used in tire tread, giving tires excellent wear resistance. Other parts of the tire, such as sidewalls, cord ply, belt bundle cushioning layer and inner liner, the rubber is required to resist flex cracking, ozone oxidation, good resilience and low heat generation performance, generally use a thicker particle size of the semi-reinforcement type (specific surface area of less than 40m2/g) furnace black.
Pigment with groove black is widely used in inks, coatings and plastics. Ink, especially news ink mainly used in the pigment slot black. In the paint manufacturing process, high pigment slot blacks give the blackness and gloss of high-grade automotive topcoats, while medium pigment slot blacks are used in general industrial coatings. In addition, the medium pigment channel black is also commonly used as polyolefin UV shielding agent, used to improve the weather resistance of plastic products. Rubber groove black is mainly used for tires, especially off-road and engineering tires tread rubber, which gives the tread high strength and good abrasion resistance.
Hot crack black is mainly used for rubber products. Due to the coarse particle size and poor reinforcing properties, only for the maximum filler incremental occasions, such as for the manufacture of rubber mats, hoses, sponge products, seals, tire liners, bead rubber and insulation products.
