Carbon Black N772
Carbon Black N772 is a low-structured, general-purpose reinforcing carbon black, widely used in rubber compounds requiring good processability, moderate reinforcement, and high elasticity. It is ideal for tire sidewalls, hoses, gaskets, and mechanical rubber components, offering excellent dispersion and flexibility.
Features
- Low-structured reinforcement – Provides flexibility and processability in rubber compounds
- Good crack and fatigue resistance – Enhances durability in dynamic applications
- Excellent dispersion – Easier to mix and process than high-structured carbon blacks
- High elasticity and resilience – Maintains rubber flexibility under mechanical stress
- Low heat buildup – Reduces internal friction, improving rubber longevity and efficiency
Applications
✔ Tire sidewalls, inner liners, and flexible rubber components
✔ Industrial rubber products, including hoses, seals, and gaskets
✔ Molded rubber parts requiring high elasticity and crack resistance
✔ Mechanical rubber components subjected to continuous stress and movement

Carbon Black N772 is a low-structure reinforcing carbon black, designed to provide good processability, flexibility, and low heat buildup. Compared to medium-structured carbon blacks like N650 or N550, N772 has lower surface area and absorption properties, making it easier to mix and disperse in rubber compounds.
Its lower reinforcement capacity compared to higher-structure grades means that N772 is best suited for applications requiring resilience, crack resistance, and good dynamic properties, rather than extreme wear resistance.
In tire manufacturing, Carbon Black N772 is commonly used in tire sidewalls, inner liners, and rubber components, helping to reduce heat buildup and improve rubber elasticity. It enhances the flexibility and longevity of rubber parts, making it ideal for applications where dynamic performance and ease of processing are key.
Beyond automotive applications, N772 is frequently used in industrial rubber products, such as hoses, seals, and gaskets, where good elasticity and dispersion are required. Its lower reinforcement effect makes it ideal for rubber components that require flexibility and durability without excessive hardness.
