What is carbon black N550
Carbon black N550 certainly is a black bead or granular or grain and amorphous solid, and actually, It features moderate wear resistance, good rubber processing, and good extrusion performance which can be used in tire inner liners, tubbing, carcass, profiles, hoses, hose cover, cable jacketing, and mainly plastic conduit compounds requiring excellent dimensional stability too.
However carbon N550 is odorless with a burning point of more than 400c, water-insoluble, non-poisonous As well as stable chemical properties, excellent weather, and light fastness, and Furthermore, this Carbon black is used in fabric cord of tire side, extrusion, and rolling compounds N550 is preferred to use with N660 too.
Usage of black N550
Mainly N550 used in many different industries such as the rubber industry, plastic, paint, and pigment industry, and although used In the cord layer of tire and sidewall of tires too.
Also N550 Improves the durability, strength and color of rubber-based materials and increases overall performance, depending on its structure and usage rate.
Actually Carbon black N550 also used in rubber industry, rubber shoes and all kinds of rubber products, And finally its correctly used in the plastic industry in medical instruments, electrical cables and adhesive properties that protect from ultraviolet rays.

A: Carbon Black N550 is a semi-reinforcing furnace carbon black grade made by the incomplete combustion of hydrocarbon feedstocks under controlled conditions. It yields fine carbon particles designed for reinforcement in rubber and industrial compounds.
A: Typical specifications include an iodine adsorption number around 43 g/kg, oil absorption number (OAN) around 121 cm³/100 g, pouring density around 360 kg/m³, ash content up to 0.45 %, heating loss at 125 °C ≤ 1.0 %, and sieve residue on 45 µm under 0.1%.
A: N550 is ideal for rubber goods such as tire carcasses, sidewalls, hoses, belts, cables and other extrusion or molded rubber parts. It is also used in plastic master-batches, inks and high-end coatings requiring moderate reinforcement and smooth finish.
