The performance of many industrial products, from tires and rubber goods to plastics and inks, is significantly influenced by the type of carbon black used. Selecting the correct grade of carbon black is a critical step in product formulation, impacting everything from mechanical strength to color intensity. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of industrial chemicals, provides expert guidance on understanding and selecting carbon black grades.

Carbon black grades are primarily categorized by their physical properties, most notably particle size and structure, which are often indicated by industry standard designations such as those from ASTM. Semi-reinforcing furnace (SRF) carbon blacks, for example, are characterized by larger particle sizes and lower structure compared to highly reinforcing grades. This makes them ideal for applications where a balance of reinforcement, flexibility, and processing ease is required.

Key Carbon Black Grades and Their Applications:

  • Reinforcing Grades (e.g., N100, N200, N300 series): These grades have small particle sizes and high structure, providing excellent tensile strength, abrasion resistance, and tear strength. They are typically used in tire treads and high-performance rubber components.
  • Semi-Reinforcing Grades (e.g., N500, N600, N700 series): With larger particle sizes and lower structure, these offer good processing characteristics, moderate reinforcement, and improved fatigue resistance. They are suitable for tire carcasses, hoses, belts, and various molded rubber goods. Our semi-reinforcing furnace carbon black, often sought as an N880 equivalent, falls into this category, offering a versatile solution for many rubber applications.
  • Specialty Grades: These include conductive carbon blacks, high-purity grades for inks and coatings, and specific types for plastics and masterbatches, each tailored for unique performance requirements like electrical conductivity or pigment dispersion.
