1. Product Introduction & Main Application
Arnico’s Industrial Carbon Black is a very fine, black powder produced from the incomplete, controlled combustion of heavy hydrocarbons in the Furnace Black process. This substance is primarily used as a reinforcing agent in the rubber and tire industry, dramatically increasing the abrasion resistance and tensile strength of rubber, and as a black pigment in paints, inks, and plastics.

3. Features & Benefits
-
High Reinforcement (N330): Provides the highest abrasion resistance for tire treads, extending their service life.
-
Easy Processing & Smooth Extrusion (N660): Excellent dispersion in the rubber matrix and a smooth surface on extruded parts.
-
UV Protection: Provides complete absorption of ultraviolet light, preventing the photo-degradation of polymers.
-
Deep Hiding Power & Jetness: The standard black pigment in the paint and ink industries.
4. Industrial Applications
-
Tire Industry: Tire treads (N220, N330), carcasses, and sidewalls (N550, N660).
-
Rubber Parts: Conveyor belts, hoses, gloves, and anti-vibration mounts.
-
Plastics Industry: Coloring and UV protection for polyethylene parts and agricultural films.
-
Printing & Packaging: The primary pigment in black printing inks and toners.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance is non-toxic, but its dust is a mechanical lung irritant. It is classified by IARC as a Group 2B (possible human carcinogen). The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in sturdy bags on pallets, in a covered, dry warehouse, away from direct sunlight and moisture.
-
Personal Protective Equipment (PPE): A P3 (N100) respirator, safety goggles, and work clothes are required.
6. Quality Assurance & COA
Arnico Carbon Black shipments are accompanied by a Certificate of Analysis (COA) detailing the iodine number, OAN, and BET surface area.
