N990 Thermal Carbon Black from Japan
N990 is a specific grade of thermal carbon black with large particle size (280 nm) and low structure, ideal for non-reinforcing rubber applications. It falls under HTS 2803.00.0010 as pure carbon black, providing electrical conductivity without affecting rubber processing. Used in wire insulation and belts.

Import Tips
• ASTM D-1618 specs confirm N990 grade classification
• Low DBP absorption (<45 ml/100g) distinguishes thermal from furnace blacks
