Carbon Black N550 High Quality Powder for Plastic Compounds

‌Material Overview‌

Carbon black is a finely engineered amorphous carbon material, characterized by its ultra-fine particle structure (10–500 nm), high surface area (25–1,500 m²/g), and exceptional light absorption capabilities. Produced through controlled thermal decomposition of hydrocarbon feedstocks under oxygen-deficient conditions, this lightweight black powder serves dual roles as a premium pigment and a critical performance enhancer across industries. Its unique combination of colloidal stability, electrical conductivity, and mechanical reinforcement properties makes it indispensable in applications ranging from tire manufacturing to advanced electronics.
