What is the biggest use of carbon black? Understanding carbon black and its uses

last edited:April 8,2023   

  Many people may not be familiar with carbon black, especially those who have never heard of it before. They may not know what carbon black looks like and what it is used for. In fact, the biggest use of carbon black is in rubber tires. Of course, carbon black has many other uses, and its application in tires is just one of them. Here, let's introduce carbon black to everyone and its various uses.

  What is carbon black?

  Carbon black, also known as charcoal black, is an amorphous form of carbon. It is a light, loose, and extremely fine black powder with a very large surface area ranging from 10 to 3000 m2/g. It is produced by the incomplete combustion or thermal decomposition of carbon-containing materials (such as coal, natural gas, heavy oil, and fuel oil) under conditions of insufficient air.

  What is the function of carbon black?

  The role of carbon black varies in different industries. In rubber tires, it mainly plays a reinforcing role, while in inks and coatings, it mainly acts as a coloring agent. In plastics, it can have various functions such as conductivity, antistatic properties, and UV resistance.

  What are the uses of various types of carbon black?

  Carbon black is mainly used as a reinforcing agent and filler in rubber, with rubber using more than 94% of the total carbon black produced. Of this, about 60% is used in the tire manufacturing industry. In addition, carbon black is also used as a coloring agent in inks, coatings, and plastics, as well as a UV shield for plastic products. It is also an important additive in electrodes, batteries, resistors, explosives, cosmetics, and polishing pastes.

  What is the use of rubber carbon black?

  Rubber springs are used in various rubber products, such as the tire industry, rubber seals, and shock absorbers. Adding a certain amount of carbon black to rubber products can enhance their performance and improve their properties. Many black rubber products now contain a certain amount of carbon black to enhance their performance. According to the carbon black's specific properties, they can be classified as N220, N234, N326, N330, N339, N375, N550, N539, N660, etc.

  What is the use of pigment carbon black?

  Pigment carbon black is mainly used as a black pigment in the ink and paint industries. It can be divided into high-pigment carbon black, medium-pigment carbon black, and ordinary-pigment carbon black based on its coloring strength, with models such as C111, C311, C611, etc.

  What is the use of conductive carbon black?

  Conductive carbon black uses the low electrical resistance or high conductivity of certain carbon blacks to make them suitable for use in different products, such as conductive rubber, electronic components, and batteries. Conductive carbon black can be classified as special conductive carbon black, super conductive carbon black, acetylene carbon black, etc.

  What is the use of white carbon black?

  White carbon black is not actually a type of carbon black. It is silica, and its performance can completely replace carbon black for use in rubber. It is called white carbon black because it is white in color. However, white carbon black and black carbon black are two different products, and it's important to note that. Nevertheless, the uses of white carbon black are similar to those of black carbon black.
