Carbon Black N330 Bkt

About Carbon Black

It is mainly used as reinforcing filler in tires and rubber products and also as colourant additives and filler in plastics, inks, coatings and other industrial applications.

Carbon Black is an additive mainly used for colouring and rubber and plastic products reinforcement. The feature that made it widespread in the industrial production is its ability to give a deep, everlasting black colour. Furthermore, it protects from UV rays and it is a guarantee of durability. We can find it in ink, pigments and colorants such as the toner of laser printers and copiers.

Composition

Carbon black contains more than 99% pure carbon. Other components are oxygen, hydrogen, and nitrogen. It is available in powder or beads (pellet) form. The black particles are 10nm to approximately 100nm in size and fuse into chain-like aggregates, which define the structure of individual grades. Depending on the production process parameters, it differ in particle size, structure, surface chemistry, porosity, and many other characteristics. The properties of most of its grades are determined by industry-wide standards.

Carbon Black Grades

Surface area measurement gives an indirect characterisation of carbon black particle size. Typical particle sizes for furnace blacks range from approximately 8 nanometers to 100 nanometers. Smaller particle size increases the specific surface area (m2/g) of the product. Smaller particle size and higher specific surface area lead to increased reinforcement, increased abrasion resistance, improved tensile strength but higher hysteresis. To disperse smaller particle size, it requires increased mixing time and energy. Particle size and its distribution can only be measured using a transmission electron microscope. Based on surface area, furnace blacks fall within N100 to N700 series. (N) denotes normal curing material.

Quality Assurance

With a wide range of Carbon black grades, BKT Carbon can fulfil users needs in numerous fields, from the manufacture of high-performance tires to all types of MRG (Mechanical Rubber Goods). BKT Carbon obtained ISO 9001: 2015 quality certification by Alcumus ISOQAR, an internationally accredited certification body, and REACH registration that certifies a greater level of human health protection and environmental safety.
