What is carbon black N660
Carbon black N660 is general purpose furnace black (GPF), It has higher structure, smaller particle size, easy to disperse, higher tensile stress and strain at break and also lower heat-up-good elasticity and fatigue properties .
Mainly GPF is black bead or granular or grain and amorphous solid, actually one of the applications of carbon black N600 in production hydraulic-brake hose of high anti fatigue it is characterized in that ,also the carbon black in the description inner glue layer raw materials is black N550, N660 , and also the percentage of shared inner glue layer raw material gross weigh.
Usage of black N660
The Carbon black N660 is suitable for various vulcanizates as well as compared to semi-reinforcement black. It’s widely used in various fields, and GPF is used in fabrics cord of tire, bicycle and inner tires, house, belt, cable, shoes, extrusion compounds and rolling compounds.
Packing of the material
Packing in double layer Kraft paper-PE envelopes ( 20-25 kg)

How we are shipping the cargo?
Depending on the grade of carbon black, we carry and load it. According to the transportation ways of the buyer country, the method of loading it changes, usually through 40-foot containers, where each container changes from at least 15,489 to at least 22 depending on the grade of carbon black and the type of packaging.

A: Carbon Black N660 is a medium-structure furnace carbon black grade produced via controlled incomplete combustion of hydrocarbon feedstock. Its structure and properties place it between reinforcing and semi-reinforcing blacks, offering balanced performance in rubber and industrial applications.
A: Typical values include an iodine adsorption around 32-40 g/kg, oil absorption number (OAN) approx 85-95 cm³/100 g, ash content up to 0.5 %, heating loss ≤ 1.5 %, sieve residue on 45 µm maximum ~0.1 %, and bulk pour density around 420-450 kg/m³.
A: N660 is widely used in rubber compounds for tyres (carcass, inner liner, bicycle tyres), hoses, belts, cables, extrusion profiles, industrial rubber goods, and in plastics masterbatches where reinforcement and processability are required.
