Carbon Black N550

Other Name:Fast Extrusion Furnace Black; FEF

Carbon black N550 has smooth particle surface and high structure, resulting in best reinforcement properties among soft carbon blacks.

Usage:

N550 is suitable for natural rubber and synthetic rubbers. It is easy to disperse, resulting in high enduring property, high extrusion rate, smooth surface, small expansion, high temperature resistance and high heat-conductive, high re-inforcement, high elasticity and rebounding properties.

Balck Carbon N550 is mainly used in fabric cord of tire, tire side, extrusion and rolling compounds. It is preferred to use with N660 when used in butyl rubber compounds.

Application:
Carbon black N550 is used in fabric cord, tire side compound, extrusion and rolling compounds, And also can be used for masterbatch.
