Carbon black N220

Description

1. Product Overview

Carbon black N220 is a high-abrasion furnace (HAF) grade, characterized by its moderate particle size (24–28 nm) and high structure, making it the industry standard for reinforcing rubber compounds requiring superior wear resistance. Its primary use is in tread compounds for truck, bus, and passenger car tires, as well as industrial mechanical goods. The key value proposition is an optimal balance of tear strength, modulus, and abrasion resistance, directly extending product lifespan. Strategically, N220 remains critical for manufacturers seeking to meet stringent durability standards without transitioning to more expensive specialty grades.

2. Key Specifications & Technical Characteristics

• Chemical composition: >97% elemental carbon, low ash (≤0.5%), minimal sulfur residues

• Purity grade: ASTM D1765 compliant, standard N220 grade (IAST G-1 rating)

• Physical characteristics: Black, fine free-flowing pellets; Iodine adsorption number: 120 g/kg; DBP absorption: 114 cm³/100g; 325-mesh sieve residue ≤0.02%

• Form & density: Pelletized; tapped density 340–400 kg/m³; true density ~1.8–1.9 g/cm³

• Packaging options: 600 kg flexible intermediate bulk containers (FIBCs), 25 kg multi-wall paper bags, or pneumatic bulk tanker truck loading

• Shelf life: 24 months from production date when stored in dry, ambient conditions (<40 °C, <60% relative humidity)

3. Core Industrial Applications

• Tire manufacturing (tread & sidewall) – N220’s high structure and moderate particle size maximize chipping, chunking, and cut-growth resistance in off-the-road (OTR) and truck tires, outperforming lower-surface-area grades in wear scenarios.

• Conveyor belts & heavy-duty hoses – Provides superior tear resistance under dynamic load cycling, reducing unscheduled downtime compared to N330 or N770.

• Mechanical rubber goods (mounts, gaskets, rollers) – Enhances modulus without excessive heat buildup, offering longer service intervals than N550 in cyclic compression.

• Cost advantage – Delivers 80-90% of the reinforcement of premium N110 (SAF) at ~60% of the material cost, making it the cost-efficient standard for high-wear components.

4. Competitive Advantages

• Quality consistency: Lot-to-lot iodine and DBP variation controlled within ±3% of target – certified via ISO 9001:2025 with FTIR fingerprinting.

• Supply reliability: Dual-sourced raw material feedstocks (coal tar and ethylene cracker oil) buffer against upstream supply shocks; 98.5% on-time-in-full (OTIF) track record.

• Logistics capability: Ability to ship in bulk pneumatic trailers (30 MT), FIBCs, or 25 kg bags via rail, ocean container, or LTL – port-adjacent warehousing in three continents lowers lead times.

• Price competitiveness: Tier-1 quality at pricing 4–7% below regional averages for comparable Asian and European grades due to energy-efficient reactor design.

• Sustainability: Available with ISCC PLUS-certified circular grades (mass balance approach, 20% bio-circular carbon content upon request).

• Technical support: Free recipe optimization consultation and full Millathane™-compatible compounding datasheet library.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20 metric tons (20,000 kg) per shipment, single grade.

• Loading capacity (MT per container):

  • 20′ dry container: 18 MT (FIBC palletized) or 20 MT (bulk bag stuffing)

  • 40′ dry container: 25 MT (FIBC)

  • Bulk pneumatic tank trailer: 24–28 MT per load (domestic US/EU only)
