Carbon Black N990 is produced by Thermal cracking processing. Generally, thermal cracking carbon black is produced by cracking natural gas with air heated to 1300 ℃. It is composed of a large amount of spherical, elliptical carbon and a small number of fusion particles. It has a large particle size, small specific surface area, low structure, easy dispersion, good fluidity, and high Filling volume and other characteristics. Because of its low surface activity, it is also called non-reinforced carbon black. It is one of the more widely used in tire inner liners, hoses, tapes, oil seals and fluoroelastomer products.
