Applications of Carbon Black
Carbon black finds a wide array of applications as a filler, influencing mechanical, electrical, and light-transmittance properties when added to various environments. Consequently, it plays a pivotal role in shaping the properties of elastomers, plastics, inks, and rubber. For instance, it bolsters ultraviolet ray protection in plastics, acts as a proficient conductor in thermoplastic polymers, and, when used as a filler in rubber, enhances parameters like abrasion resistance, wear resistance, scratch resistance, and toughness.
Given its unique chemical composition, coloration properties, particle size, and colloidal attributes, carbon black enjoys extensive use in various industries, with the rubber industry being a primary beneficiary. Typically, it comprises around 25-30% of the weight of rubber. Beyond serving as a filler, carbon black imparts considerable strength to rubber due to its varied properties. Its most prevalent use, after the rubber industry, is found in the ink sector, especially in newspaper printing, paint, coatings and the plastic industry
Within the realm of plastics and associated products, carbon black is employed for coloration, heat protection, guarding against degradation caused by ultraviolet radiation, modification of electrical properties, and reinforcement. It is occasionally employed in the industry as a rejuvenating agent, playing a pivotal role in shaping the characteristics of elastomers, plastics, inks, and rubber. Particularly in the tire industry, approximately 80% of the produced carbon black is consumed.
