Carbon black is a critical reinforcing agent used in the rubber and plastic industries. It enhances strength, wear resistance, and durability across a variety of applications. The rubber industry primarily uses two types of carbon black, each offering distinct performance characteristics.
⸻
Types of Carbon Black
Hard Carbon Black (N100–N300 Series)
Known for its high abrasion resistance, hard carbon black is commonly used in the production of vehicle tire treads. It imparts stiffness, toughness, and low resilience to rubber compounds, making it ideal for high-wear applications.
Soft Carbon Black (N500–N700 Series)
Designed for flexibility, soft carbon black is used in components such as tire carcasses, where significant flexing occurs. It provides a softer, more elastic, and resilient rubber compound while maintaining strength and durability.
Note: The production processes of hard and soft carbon black differ significantly, resulting in distinct physical and reinforcing properties.
