Carbon black - Wikipedia

The most common use (70%) of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The balance is mainly used as a pigment in inks, coatings and plastics. Carbon black is added to polypropylene because it absorbs ultravioletradiation, which otherwise causes t…

Black carbon - Wikipedia

Chemically, black carbon (BC) is a component of fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter). Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle in both anthropogenic and naturally occurring soot. Black carbon causes human morbidityand premature mortality. Because of these human health impacts, many countries have worked to reduce their emissions, makin…

What is Carbon Black? | Carbon Black 101 | Birla Carbon

It is produced by partial burning and pyrolysis of low-value oil residues at high temperatures under controlled process conditions. Carbon black 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.

While the fundamental building block of carbon black is the primary particle, these never exist in isolation, but are strongly fused by covalent bonds into aggregate. The primary particles are thus conceptual in nature since once the aggregate is formed the primary particles no longer exist as discrete entities and have no physical boundaries among them. Once produced, individual aggregates ...
