Carbon Black N550 (FEF)
Carbon Black N550, classified as Fast Extrusion Furnace (FEF), is a semi-reinforcing carbon black prized for its excellent processing characteristics in extrusion applications. It provides good tensile strength and tear resistance while offering smooth extrudate surfaces, low die swell, and high extrusion rates. N550 is widely used in tire inner liners, wire and cable insulation, hoses, and profiles where processability is as important as reinforcement.
