Carbon Black N550
Introduction
Among the various grades of carbon black, Carbon Black N550 stands out for its unique properties and wide-ranging applications.
Carbon Black N550, also known as channel black, is a type of carbon black that falls under the ASTM (American Society for Testing and Materials) classification. It is produced through the partial combustion of heavy petroleum products, resulting in fine particles of carbon. These particles are structured in such a way that they form small, interconnected channels, which give the material its distinctive name.
Properties and Characteristics:
- Particle Size: Carbon Black N550 is characterized by a relatively large primary particle size, typically ranging from 20 to 50 nanometers. This size imparts unique properties to the material, making it suitable for various applications.
- Structure: The interconnected channel structure of N550 carbon black enhances its reinforcing capabilities, making it a valuable ingredient in the rubber industry. It improves the mechanical properties of rubber products, including tensile strength, abrasion resistance, and tear resistance.
- Surface Area: N550 has a substantial surface area due to its particle size and structure. This property makes it an excellent adsorbent, finding applications in ink formulations, plastics, and coatings as a pigment and UV stabilizer.
