Carbon Black N110

Updated: 2026-07-24

Overview

Carbon Black N110 is a furnace-grade carbon black classified by ASTM D1765 as a high-abrasion furnace (HAF) black. It's among the most widely used reinforcing fillers in the rubber industry due to its balanced properties. The material is produced through incomplete combustion of heavy petroleum products under controlled conditions. With its small particle size (20-25 nm) and high surface area, N110 provides exceptional reinforcement to rubber compounds. This grade is particularly valued in applications requiring durability and abrasion resistance. Industry standards strictly govern its production to ensure consistent quality across batches.

Physical and Chemical Properties

N110 exhibits a typical carbon black structure with a high surface area of 125-145 m²/g as measured by nitrogen adsorption (BET method). Its structure, quantified by dibutyl phthalate (DBP) absorption, ranges between 113-127 cm³/100g. The material is chemically inert under normal conditions but can oxidize at extremely high temperatures. The primary particles form aggregates that create a reinforcing network within rubber matrices. Its tinting strength is approximately 124% relative to IRB3 reference black. The volatile content is typically below 1.5%, ensuring minimal impact on compound viscosity during processing.

Main Applications

Approximately 70% of N110 consumption goes into tire manufacturing, particularly for tread compounds where abrasion resistance is critical. It significantly improves treadwear performance while maintaining acceptable rolling resistance. The material is also specified in off-the-road (OTR) tire applications. Beyond tires, N110 serves in industrial rubber products like conveyor belts, hoses, and vibration isolators. Some specialty applications include anti-static components and mechanical rubber goods requiring high tensile strength. In non-rubber applications, it's occasionally used as a UV stabilizer in plastics and as a pigment in inks.

Safety and Storage

As a fine particulate, N110 requires careful handling to prevent dust formation. Facilities should employ local exhaust ventilation and require workers to wear NIOSH-approved N95 respirators. The material presents a potential dust explosion hazard (Kst >300 bar·m/s), necessitating proper grounding of equipment. Bulk storage should maintain relative humidity below 65% to prevent caking. Super sacks or carbon black-specific silos are preferred over paper bags for large quantities. Firefighting requires dry chemical or carbon dioxide extinguishers—water application may create steam explosions due to the material's high thermal mass.

B2B Procurement Guide

Industrial buyers should verify certification to ASTM D1765 or ISO 4652 standards. Key specifications to request include sieve residue (max 0.001%), ash content (max 0.5%), and heating loss (max 1.5%). For rubber applications, request compound performance data including Mooney viscosity and Payne effect measurements. Leading manufacturers typically offer technical support for compound formulation. Consider regional availability—bulk shipments by railcar or tanker truck offer cost advantages over bagged product. Just-in-time delivery models are practical given carbon black's extended shelf life when properly stored.
