Carbon black is a high-tech material with properties that conform to international standards and are crucial for determining the character of end products. For example, as a filler material, carbon black improves the mechanical characteristics of plastic, increases the abrasion-resistance of tires, and offers protection against heat and UV radiation. Depending on their characteristic properties, thePigment Carbon Black types are suitable for all different kinds of application.
The table below shows the impact of particle size and structure on the characteristic properties of carbon black. The specific surface becomes larger as particle diameters decline. For this reason carbon black with smaller particles absorbs greater amounts of oil.
Particle size & structure characterize the properties of CB
Since small particles also aggregate more easily than large ones, a smaller particle size results in increased viscosity. Blends with (“hard”) carbon blacks (Carbon Black N550 and smaller) of a small particle size and high structure solidify rubber compounds better and hence yield rubber products with high abrasion resistance and low elasticity.
These are particularly suitable for tire treads. Accordingly, the tire industry places the toughest requirements on the quality and properties of carbon black. Tests to determine the quality and applicability of the Beilum carbon blacks which were conducted by renowned tire manufacturers independently of one another have yielded very positive results. Tests of the characteristics (surface, structure) have demonstrated that Beilum carbon black achieves values that are similar to those of Carbon Black N326 and Carbon Black N330, and that it can replace N660 and N772. Beilum carbon black is between the so-called hard and soft carbon black types, which gives it a very broad application range.
