Carbon black is a nanoscale black powder generated by incomplete combustion/thermal cracking of hydrocarbon raw materials. It is the most core reinforcing filler in rubber formulations and the highest proportion of powder raw materials in tire formulations. It is often used in combination with stearic acid, zinc oxide, aromatic oil, and 6PPD. 
-Appearance: Black ultra-fine powder, mostly made into granular carbon black in the market (reducing dust and facilitating feeding) 
-Mainstream furnace charcoal black plate number (ASTM N series) 
-N110: Super reinforced, minimum particle size, high wear resistance, high-performance tread 
-N220/N234: High reinforcement, heavy-duty tires, high-performance tire tread 
-N330: Universal ace, passenger tire tread, conveyor belt, rubber parts 
-N550: Good extrusion performance, sidewall, hose, extruded rubber material 
-N660: Low heat generation, tire body, inner tube, shock-absorbing rubber 
-Packaging: 25kg laminated woven bag 
>Principle: The surface active groups of carbon black nanoparticles form a strong bond with rubber molecular chains, greatly enhancing the mechanical strength of rubber; Pure rubber without carbon black reinforcement has extremely poor wear resistance and tires quickly wear out. 
Core Advantages 
1. Super strong reinforcement, significantly improving mechanical performance 
Significantly improving the tensile strength, tear strength, hardness, and tensile stress of vulcanized rubber, transforming it from a soft elastic material to a high-strength wear-resistant material, is the foundation of tire durability. 
2. Significantly improve wear and cutting resistance performance 
High reinforcement carbon black such as N110/N220/N234 directly enhances the wear mileage, anti chipping, and anti cutting properties of tire treads, making it the most critical raw material for tire treads. 
3. Absorb ultraviolet rays to assist in aging resistance 
Carbon black can absorb ultraviolet light, prevent ultraviolet light from damaging rubber molecules, and with 6PPD antioxidant, it can double improve the weather resistance and aging resistance of rubber. 
4. Adjustable dynamic heat generation and rolling resistance 
Different particle sizes and structures result in significant differences in dynamic performance: fine particle high structure carbon black has good wear resistance but high heat generation; Coarse particle grades (N550/N660) have low heat generation and good elasticity, suitable for sidewall and carcass. 
5. Coloring+shielding, good stability 
Strong black coloring power, chemically inert, acid and alkali resistant; Rubber can also be endowed with conductive/anti-static functions (special conductive carbon black). 
6. Strong processing adaptability 
Granular carbon black has low dust emission, and during mixing, it quickly infiltrates and disperses in the rubber material under the dispersing effect of stearic acid; Paired with aromatic oil, the mixing process is smoother. 
Main applications 
-Tires: tread (N220/N330/N234), sidewall (N550), carcass/air tight layer (N660) 
-Industrial rubber: conveyor belts, rubber hoses, shock absorbers, seals, rubber rollers, solid tires 
-Other: Plastic colorants, inks, coatings, conductive rubber
