Carbon Black N330
Functional Fillers & Reinforcing Agents
Carbon Black N330.
BOAO N330 is a versatile semi-reinforcing carbon black offering an optimal balance between surface area and processing ease. With good tint strength (96–112 m²/kg) and controlled particle size distribution, N330 provides reliable reinforcement across a wide range of rubber compounds. Its moderate surface area and oil absorption characteristics make it ideal for applications requiring balanced properties without excessive processing demands. Primary Applications: General-purpose tyre treads, conveyor belts, industrial rubber compounds, mechanical goods Secondary Applications: Shoe soles, gaskets, seals, industrial hose compounds, rubber rollers
