What is this Black Color chemical called as CARBON BLACK?

Carbon black is a fine black powder produced from hydrocarbons through controlled combustion processes. It is widely used as a reinforcing filler and black pigment in industries such as rubber, plastics, inks, and coatings due to its excellent strength, durability, and coloring properties.

Properties & Grades

Particle size is an important property of carbon black that affects reinforcement, conductivity, and tinting strength. Smaller particles provide better strength and surface area but require higher mixing and dispersion energy.

Particle Size

Structure

Structure refers to the three-dimensional arrangement and branching of carbon black aggregates. Higher structure improves conductivity, hardness, modulus, and dispersibility, but also increases compound viscosity.

Porosity

Porosity is the presence of tiny pores within carbon black particles formed during manufacturing. Higher porosity increases surface area, conductivity, and compound loading capacity while maintaining lower specific gravity.

Surface chemistry refers to oxygen-containing groups on the carbon black surface due to manufacturing and heat treatment. It affects dispersion, wettability, conductivity, and tensile properties in rubber compounds.
