The world of carbon black is vast, with numerous grades designed for specific industrial needs. Understanding the differences between these grades is essential for procurement managers and R&D scientists seeking to optimize their products. This article compares our G785 regenerated carbon black with other common grades, highlighting its unique advantages. As a reputable carbon black supplier, we aim to clarify these distinctions.

Carbon black grades are primarily differentiated by their physical and chemical properties, such as particle size, surface area, structure, and tinting strength. These properties dictate their performance in various applications like rubber reinforcement, pigmentation, and conductivity.

Key Carbon Black Grade Categories and Their Properties:

Furnace Blacks: These are the most common types, produced via the furnace process. They are further categorized by their typical properties, often indicated by a numerical system (e.g., N-series by ASTM or R-series by ISO):

  • Large Particle Size/Low Surface Area (e.g., N774, N660): These grades offer good processing safety, lower viscosity, and moderate reinforcement. They are often used in applications where high loadings are required, such as tire carcasses, sidewalls, and general rubber goods.
  • Medium Particle Size/Medium Surface Area (e.g., N550, N330): These grades provide a balance of reinforcement, abrasion resistance, and processing ease. N550 is frequently used in tire sidewalls and treads, while N330 is known for its excellent abrasion resistance, making it suitable for tire treads and high-performance belts.
  • Small Particle Size/High Surface Area (e.g., N220, N110): These grades offer superior reinforcement, abrasion resistance, and higher tensile strength. N220 is a high-performance tread compound carbon black, and N110 is used for the most demanding applications requiring maximum wear resistance.

Our G785 Regenerated Carbon Black:

Our G785 is a regenerated carbon black, meaning it's produced from recycled tires. It is characterized by:

  • Spherical Granules and Small Particle Size: Similar to some fine furnace blacks, G785 offers a small particle size.
  • High Specific Surface Area: This contributes to good reinforcement properties.
  • Excellent Mechanical Properties: It provides higher constant elongation stress and tear strength, improved processing performance, and reduced mixing time compared to some conventional grades.
  • Eco-Friendly: Made from recycled tires, it offers a sustainable alternative.

Comparison with Key Grades:

  • vs. N660/N550: G785 generally offers superior tensile strength and processing advantages, potentially replacing these grades in certain applications or offering a more sustainable option with comparable performance.
  • vs. N330/N220: While N330 and N220 are known for exceptional abrasion resistance, G785 provides a strong balance of reinforcement, processing ease, and sustainability, making it a compelling choice for many rubber compounds and other applications.
