Carbon black N330

Description

1. Product Overview
Carbon Black N330 is a high-reinforcing furnace-grade carbon black produced from controlled hydrocarbon pyrolysis. It is primarily used as a reinforcing filler in rubber compounds, especially in tire treads, sidewalls, and industrial mechanical goods. The key value proposition lies in its optimal balance of abrasion resistance, tear strength, and extrusion smoothness. Strategically, it remains the global benchmark for general-purpose reinforcement, enabling manufacturers to achieve durability without excessive compound viscosity.

2. Key Specifications & Technical Characteristics

• Chemical composition: >97% elemental carbon, low ash and sulfur residuals

• Purity level: Typical purity ≥99.5% on dry basis

• Physical characteristics: Black pellets; Iodine absorption number 82 ± 7 g/kg; DBP absorption number 102 ± 7 cm³/100g; 35 nm average particle size; 1.8 g/cm³ typical density

• Packaging options: 25 kg paper bags, 500 kg semi-bulk FIBCs, or bulk pneumatic tanker

• Shelf life: 24 months in original unopened packaging under dry, ambient conditions

3. Core Industrial Applications

• Tire manufacturing: Tread compounds, sidewall blends, and carcass ply – enhances wear resistance and fatigue life by 15–20% versus soft grades

• Rubber mechanical goods: Conveyor belts, hoses, gaskets, and automotive mounts – improves tear strength and dynamic flex resistance

• Masterbatch production: Provides consistent jetness and dispersion for black plastics and EPDM profiles

• Performance advantage: Low hysteresis relative to N220 reduces heat buildup in dynamic applications, lowering energy loss and improving part longevity

4. Competitive Advantages

• Quality consistency: ISO 19001-controlled production with batch-to-batch CV <3% on key parameters (iodine, DBP)

• Supply reliability: Triple-sourced feedstock agreements and buffer stock of 1,500+ MT across regional hubs

• Logistics capability: Containerized, break-bulk, and pneumatic tanker delivery with 7-day lead time to major ports

• Cost competitiveness: Direct mill pricing with volume-indexed discounts, removing 2–3 distribution layers

• Sustainability: 12% of energy input from recovered off-gas; full traceability and technical datasheet library available on request

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (bulk)

• Loading capacity: 20–25 MT per 20-foot dry container (depending on bagging or bulk bags)
