determination of carbon black in rubber products of liberia
Carbon Black Analyses | Polymer Chemical Characterization
Carbon black can be one of the most important raw materials in a rubber product formulation. Many rubber products where tensile and abrasion properties are crucial use carbon black. Adjustments in type or quantity can affect these properties as well as hardness, tear strength, and electrical conductivity, to name a few.

Determination of carbon black in rubber products
Determination of carbon black in rubber products. The difference is that the different rubber require different operating conditions, such as the extraction time, the extraction of the solvent used in the choice of solvent, rinsing of residue, and the processing temperature. These two processes see the standard GB 7766-87 and GB 3515-83.

Use of Carbon Black - Polymer Solutions
How carbon black functions in products. When used in tires and other rubber products, it’s primarily a filler, taking the place of more costly binder materials. As a filler in tires, carbon black also helps extend the life of the tire by conducting heat away from the tread and belt area. It also acts as a pigment, making rubber materials black.
