Detailed application areas and performance of carbon black

Carbon black manufacturers explain the main application of carbon black

 The main application of carbon black

It is mainly used as a reinforcing agent and filler for rubber. Its consumption is about half of the rubber consumption. Rubber carbon black accounts for 94% of the total carbon black, of which about 60% is used in tire manufacturing. In addition, it is also used as a coloring agent for inks, paints and plastics, and as an ultraviolet light shielding agent for plastic products. It is also an important adjuvant in many other products such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes.

Furnace black is mainly used for rubber products. The finer the particle size of carbon black, the better its reinforcing performance; the higher the carbon black structure, the higher the modulus and modulus. The fine-grained reinforcing type is mainly used for tire treads, giving the tire excellent wear resistance. Other parts of the tire, such as the sidewall, the ply, the belt buffer layer and the inner liner, require the rubber to resist cracking, ozone oxidation, good resilience and low heat build-up. A semi-reinforcing type (specific surface area below 40 m2 / g) of coarse particle size.

Groove black for pigments is widely used in inks, coatings and plastics. Ink, especially news ink, mainly uses medium pigment slot black. In the paint manufacturing process, high pigmented black gives excellent blackness and gloss to high-grade automotive finishes, and medium pigmented black is used in general industrial coatings. In addition, medium pigment black is also commonly used as an ultraviolet light shielding agent for polyolefins to improve the weather resistance of plastic products. Slot black for rubber is mainly used for tread rubber for tires, especially for off-road and engineering tires, which gives the tread a high strength and good wear resistance.

Thermal cracking black is mainly used for rubber products. Due to the coarse particle size and poor reinforcing performance, it is only used in applications requiring maximum filling increments, such as in the manufacture of rubber pads, hoses, sponges, seals, tire inner liners, bead rubber and insulation products.
