In the vast spectrum of rubber compounding, selecting the right reinforcing agent is key to achieving desired product properties while managing costs. Carbon black N660, a High Modulus Furnace (HMF) grade, offers a strategic balance of semi-reinforcement, good processing characteristics, and economic efficiency. As a leading chemical supplier in China, we provide high-quality N660 carbon black, making it accessible for a wide range of applications. This article highlights the benefits and uses of N660 for manufacturers seeking reliable and cost-effective solutions.

Understanding N660 Carbon Black's Properties

N660 carbon black is characterized by its larger particle size and lower surface area compared to finer reinforcing grades. This morphology contributes to its specific performance profile:

  • Semi-Reinforcement: N660 provides a moderate increase in tensile strength, modulus, and tear resistance. While it doesn't offer the extreme abrasion resistance of grades like N220 or N330, it significantly improves the overall mechanical integrity of the rubber compared to unreinforced compounds.
  • Good Extrusion and Processing: Its larger particle size and structure facilitate easier dispersion into rubber matrices. This leads to better processability, enabling higher extrusion rates and smoother molding operations.
  • Lower Hysteresis: Compared to finer carbon blacks, N660 generally exhibits lower heat buildup during dynamic flexing, which can be advantageous in certain applications.
  • Cost-Effectiveness: Typically, N660 is more economically priced than finer reinforcing grades, making it an attractive option for cost-sensitive applications where high-end abrasion resistance is not the primary requirement.

Diverse Applications of N660 Carbon Black

The balanced properties and cost-effectiveness of N660 carbon black make it a popular choice for a wide array of general rubber goods and specific tire components:

  • Tire Inner Liners: Its low gas permeability and good processability are vital for the function of inner liners, which maintain tire inflation pressure.
  • Tire Sidewalls and Beading: N660 provides adequate reinforcement for these areas, contributing to the tire's structural integrity and flexibility.
  • General Rubber Goods: It is widely used in the production of footwear components, hoses, belts, seals, gaskets, and molded parts where good mechanical properties and reasonable cost are required.
  • Extruded Products: Its excellent extrudability makes it suitable for profiles, tubing, and seals requiring consistent dimensions and smooth surfaces.
