Carbon Black N550
Carbon Black N550 is a medium-structured, general-purpose reinforcing carbon black, widely used in tire sidewalls, industrial rubber products, and mechanical rubber components. It provides good wear resistance, flexibility, and processability, making it ideal for applications requiring a balance between reinforcement and elasticity.
Features
- Moderate reinforcement – Provides strength while maintaining flexibility
- Good wear resistance – Enhances durability in dynamic applications
- Excellent dispersion – Easier to mix than high-structured carbon blacks
- High elasticity and resilience – Maintains rubber flexibility without compromising durability
- Low heat buildup – Reduces internal friction, improving rubber longevity
Applications
✔ Tire sidewalls, inner liners, and rubber components
✔ Industrial rubber products, including hoses, gaskets, and belts
✔ Molded rubber parts requiring good flexibility and durability
✔ Vibration-dampening materials and mechanical rubber goods

Carbon Black N550 is a versatile reinforcing carbon black, offering moderate reinforcement properties, excellent dispersion, and good flexibility. It is commonly used in rubber compounds where a balance of durability, tensile strength, and processability is required.
Compared to higher-structured grades like N330 and N375, N550 has lower structure and surface area, making it easier to mix and process. This leads to improved elasticity and resilience, making it ideal for applications requiring a softer, more flexible rubber compound.
In tire manufacturing, Carbon Black N550 is widely used in tire sidewalls, inner liners, and rubber components to enhance flexibility and crack resistance while maintaining good mechanical strength.
Beyond automotive applications, N550 is frequently used in industrial rubber products, such as hoses, gaskets, and vibration-dampening materials. Its excellent dispersion properties allow for efficient processing, making it a preferred choice for applications where ease of mixing and uniformity are important.
With its balanced properties of reinforcement, elasticity, and processability, Carbon Black N550 is a cost-effective and reliable choice for a wide range of rubber formulations.
