Carbon Black N650
Carbon Black N650 is a medium-structured, reinforcing carbon black, widely used in tire sidewalls, industrial rubber, and mechanical rubber products. It provides good abrasion resistance, high elasticity, and excellent dispersion, making it ideal for applications requiring durability and flexibility.
Features
- Moderate reinforcement – Enhances mechanical strength while maintaining flexibility
- Good wear and crack resistance – Increases product lifespan in dynamic applications
- Excellent dispersion – Easier to mix and process than high-structured carbon blacks
- High elasticity and resilience – Maintains flexibility under mechanical stress
- Low heat buildup – Reduces internal friction, improving rubber longevity
Applications
✔ Tire sidewalls, inner liners, and rubber components
✔ Industrial rubber products, including hoses, belts, and gaskets
✔ Molded rubber parts requiring high elasticity and wear resistance
✔ Mechanical rubber components subjected to continuous stress and movement

Carbon Black N650 is a versatile reinforcing carbon black, designed to offer a balance between reinforcement and elasticity. Its moderate structure and optimized particle size allow for easy dispersion and processing, making it a preferred choice for applications where flexibility and resilience are crucial.
Compared to higher-structured grades like N550, N650 has lower surface area and structure, which results in improved elasticity, lower heat buildup, and enhanced crack resistance. This makes it ideal for rubber products that need to withstand dynamic stress and deformation.
In tire manufacturing, Carbon Black N650 is commonly used in sidewalls, inner liners, and other rubber components, helping to increase flexibility, reduce cracking, and improve long-term durability.
Beyond automotive applications, N650 is widely used in industrial rubber products, such as hoses, belts, gaskets, and molded rubber components. Its low heat buildup and high resilience make it a great option for rubber parts exposed to continuous mechanical movement and stress.
With its optimized balance of reinforcement, elasticity, and durability, Carbon Black N650 is a cost-effective and efficient solution for a variety of rubber applications.
