Application
Carbon black is a very important additive to the rubbers that supports ELASTOMERS to improve mechanical properties.Black is used for light protection, coloring, and increasing the transmission properties. Decreasing the used rubber amount and its price to achieve mechanical efficiency and increasing operational efficiency as resistance rubbing causes the cost saving.
