Carbon Black N550 (Fast Extrusion Furnace Black, FEF)

Low reinforcing carbon black with excellent processing properties, easy dispersion, fast extrusion speed, and smooth surface finish.

Vulcanized rubber exhibits good flexibility and crack propagation resistance, suitable for fatigue-resistant rubber products.

Superior high-temperature performance and thermal conductivity, ideal for applications with lower abrasion resistance requirements.

Product details parameters

Tire carcasses, sidewalls, and inner tubes.

Hoses, calendered products, and rubber seals.
