Carbon Black N550
Functional Fillers & Reinforcing Agents
Carbon Black N550.
BOAO N550 is a cost-effective semi-reinforcing carbon black with moderate surface area and well-balanced properties for general industrial applications. The controlled particle structure ensures good dispersion and processing characteristics while maintaining adequate reinforcement performance. N550 is commonly used in applications where processing ease and economic value are priorities alongside performance requirements. Primary Applications: General rubber compounds, industrial hose covers, mechanical rubber goods, footwear compounds Secondary Applications: Weather stripping, gaskets, vibration dampers, non-critical rubber components
