Carbon Black (Hard)

What is Carbon Black?

Carbon black [C.A.S. NO. 1333-86-4] is virtually pure elemental carbon in the form of colloidal particles that are produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions. Its physical appearance is that of a black, finely divided pellet or powder. Its use in tires, rubber and plastic products, printing inks and coatings is related to properties of specific surface area, particle size and structure, conductivity and color. Carbon black is also in the top 50 industrial chemicals manufactured worldwide, based on annual tonnage.

Description:

Hard carbon black which imparts high wear resistance to rubber into which it has been compounded. Hard carbon black is generally used to make vehicular tire treads. Hard carbon blacks are commonly classified as being in the N100, N200, or N300 series.

Features:

Gives high wear-resistance, high resistance to rupture, tear resistance to rubber, high dynamic hardness and elastic rebound to rubber, high durability, and low hysteresis

Applications:

Widely used for producing: high quality, protecting rubbers and protecting stocks, transporter and conveyor belts, breaker rubber, technical seals, cable covers. It is also used for producing high quality rubber molded articles working in hard conditions.
