Detailed comparison of carbon black grades, their properties, and optimal applications in rubber, plastics, inks, and coatings industries.
What is Carbon Black?
Carbon black (CAS: 1333-86-4) is a fine black powder produced by incomplete combustion of hydrocarbons. It serves as a reinforcing filler in rubber and a pigment in various applications.
Common Grades
N330 Grade
High abrasion furnace black with excellent reinforcement properties, ideal for tire treads and mechanical rubber goods.
N550 Grade
Medium thermal black offering good processing characteristics for industrial rubber products and conveyor belts.
Key Applications
- Tire Manufacturing: Improves wear resistance and traction
- Industrial Rubber: Enhances tensile strength and durability
- Plastics: Provides UV protection and conductivity
- Inks & Coatings: Delivers deep black color and stability
Quality Parameters
Important specifications include nitrogen surface area, DBP absorption, tint strength, and residue content.
