For procurement managers and product development teams across various manufacturing sectors, sourcing the right raw materials is a cornerstone of success. Carbon black, a critical pigment and reinforcing filler, is no exception. Among the available grades, Carbon Black G685 stands out for its quality and versatility. This guide, provided by NINGBO INNO PHARMCHEM CO.,LTD., your trusted China manufacturer and supplier, aims to equip you with the knowledge needed to confidently buy and integrate this essential material into your supply chain.

Understanding Carbon Black G685: The Essentials

Carbon Black G685 is a regenerated carbon black derived from post-consumer tires. The manufacturing process ensures a high-purity product with specific physical and chemical properties that lend themselves to a variety of industrial applications. Its key attributes make it a superior choice:

  • Physical Characteristics: G685 is typically presented as a black granular product. Its spherical granule shape, small particle size, and large specific surface area are critical for its performance as a reinforcing agent and pigment.
  • Performance Enhancements: When used in rubber, it significantly improves tensile strength, tear strength, and abrasion resistance. In paints, inks, and coatings, it provides excellent tinting strength, opacity, and UV protection.
  • Processing Advantages: The material is designed for good processability, contributing to shorter mixing times and reduced energy consumption, which is a significant factor for production efficiency.
  • Sustainability Factor: As a regenerated material, Carbon Black G685 offers an environmentally conscious sourcing option, aligning with corporate sustainability goals and circular economy initiatives.

Key Specifications to Consider When You Buy

When evaluating Carbon Black G685 from a supplier, several technical specifications are paramount:

  • DBP Oil Absorption Value: This indicates the structure and reinforcing potential of the carbon black. A higher DBP absorption generally correlates with better reinforcement.
  • Iodine Absorption Value: This measures the surface area of the carbon black, influencing its pigmenting power and dispersibility.
  • Specific Surface Area (BET): A higher BET surface area typically means better reinforcement and pigmentary properties.
  • Ash Content: Lower ash content signifies higher purity.
  • pH Value: For certain applications, the pH of the carbon black can be important for compatibility and stability.
