At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the performance of your products often hinges on the precise selection of raw materials. Carbon black, a versatile chemical auxiliary agent, comes in various grades, each with unique characteristics tailored for specific industrial applications. This article delves into some of the most commonly used grades: N220, N330, and N550, and highlights their critical roles.

Carbon Black N220 is renowned for its high surface area and structure, offering excellent reinforcing properties. This makes it a preferred choice in the tire industry, particularly for tread compounds that require high abrasion resistance and strength. It is also used in industrial rubber goods where durability under demanding conditions is essential. The ability to significantly improve rubber wear properties makes N220 a high-performance additive.

Carbon Black N330 offers a balance between reinforcement and processability. It provides good abrasion resistance and tensile strength, making it a versatile option for a wide range of rubber products, including tires, belts, and hoses. Its good dispersibility also aids in manufacturing efficiency. Many manufacturers look to a reliable carbon black N330 supplier to ensure consistent quality for their production lines.

Carbon Black N550 is characterized by a larger particle size and lower surface area compared to N220 and N330, but it still offers good reinforcing capabilities. It is commonly used in tire sidewalls and carcasses, as well as in various industrial rubber products. N550 contributes to good dynamic properties and processability, making it a staple in many rubber formulations. The specific carbon black N550 applications often involve optimizing the balance between performance and manufacturing ease.

These grades, along with others like N660, represent the backbone of many industrial processes. Their precise specifications, including Iodine Absorption Number and Tinting Strength, dictate their suitability for different end-uses. For example, grades with higher Iodine Absorption Numbers generally offer greater reinforcement.
