NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive range of carbon black products tailored for the rubber industry. Among the most commonly utilized grades are N220 and N330, each possessing distinct characteristics that make them suitable for different rubber applications. Understanding these differences is key to optimizing product performance.

Carbon Black N220 is renowned for its high reinforcing capabilities and superior abrasion resistance. It features a smaller particle size and higher surface area compared to N330, which translates to greater reinforcement of the rubber matrix. This makes N220 an excellent choice for applications where extreme wear resistance is paramount, such as in tire treads, high-performance industrial belts, and heavy-duty hoses. The enhanced strength provided by N220 contributes significantly to the longevity and durability of rubber components under severe operating conditions.

Carbon Black N330, on the other hand, offers a more balanced profile of properties. It has a larger particle size and lower surface area than N220, which results in good reinforcement, improved processing characteristics, and better tensile strength. N330 is a versatile grade widely used in various rubber products, including tire sidewalls, conveyor belts, and general rubber goods. Its balanced performance makes it a cost-effective solution for applications that require good mechanical properties without the extreme demands met by N220.

When selecting between N220 and N330, manufacturers consider the specific performance requirements of their rubber products. For applications demanding the highest levels of abrasion resistance and durability, N220 is often the preferred choice. For formulations where a balance of strength, processability, and cost-effectiveness is needed, N330 proves to be an excellent option. NINGBO INNO PHARMCHEM CO.,LTD. provides technical support to help customers choose the optimal carbon black grade for their unique needs, ensuring that their rubber products achieve the desired performance characteristics. The consistent quality and purity of these carbon black grades are fundamental to achieving reproducible results in rubber compounding.
