 N375

OTHER NAME

High abrasion furnace black-high structure （New technology）；HAF-HS（New technology）

PHYSICAL AND
CHEMICAL PROPERTIES

Carbon black N375 is another grade of high abrasion furnace black with high structure (new technology). Its structure is a little lower than N339, and its properties are similar as N339. Its iodine adsorption value is 90 g/kg, and DBP adsorption is 114cm3/100g.

APPLICATION

The application of carbon black N375 is similar as N339, mainly used in the tread compounds of passenger tire, truck tire and cross-country tire. It is also used in coating compounds of conveyor belt.

USAGE AND FUNCTION

The usage and function of carbon black N375 is similar as carbon black N339 although the structure and heat-up is a little lower than N339.

10. N539

OTHER NAME

Fast Extrusion Furnace Black –low Structure ; FEF-LS

PHYSICAL AND
CHEMICAL PROPERTIES

Its iodine adsorption value is 43 g/kg, and DBP adsorption is 111cm3/100g.Carbon black N539 is derived from carbon black N550. Its structure is lower than N550. Carbon black N539 with intermediate re-inforcement property is a general-purpose furnace black.

APPLICATION

Carbon black N539 is used in carcass compound, especially suitable for buffering layer compound with natural rubber base. It is also used in the matrix compound of tire, coating compound of belt and other rubber products as well as wire and cable compounds.

USAGE AND FUNCTION

The compound filled with N539 has smooth extrusion surface, small swelling rate, high tensile strength and high elongation. The N539 compound has lower tensile stress than N550 compound. The N539 compound has good elasticity and fatigue resistance properties.

11. N550

OTHER NAME

Fast Extrusion Furnace Black; FEF

PHYSICAL AND
CHEMICAL PROPERTIES

Its iodine adsorption value is 43 g/kg, and DBP adsorption is 121cm3/100g. Carbon black N550 has smooth particle surface and high structure, resulting in best reinforcement properties among soft carbon blacks.

APPLICATION

Carbon black N550 is used in fabric cord, tire side compound, extrusion and rolling compounds.

USAGE AND FUNCTION

Carbon black N550 is suitable for natural rubber and synthetic rubbers. N550 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. Carbon black N550 is mainly used in fabric cord of tire, tire side, extrusion and rolling compounds. Carbon black N550 is preferred to use with N660 when used in butyl rubber compounds.

12. N660

OTHER NAME

General Purpose Furnace Black ; GPF

PHYSICAL AND
CHEMICAL PROPERTIES

Its iodine adsorption value is 36 g/kg, and DBP adsorption is 90cm3/100g.
Carbon black N660 has high tensile stress, good processing performance, high rebounding performance and high flexibility. It is widely used in various fields.

APPLICATION

Carbon black N660 is used in fabric cord of tire, inner tire, bicycle tire, hose, belt, cable, shoes, extrusion compounds and rolling compounds.

USAGE AND FUNCTION

Carbon black N660 is suitable for various vulcanizates. Compared to semi-reinforcement blacks, carbon black N660 has higher structure, smaller particle size, easy to disperse, higher tensile stress and strain at break, lower heat-up, good elasticity and fatigue properties. The deficiency carbon black N660 is the low elongation.
