Detail

　　The company mainly uses a new process of carbon black wet granulation technology to produce carbon black.
　　① Carbon black for tires
　　According to the performance of carbon black in tire rubber compounds, the rubber carbon black produced by the company can be further subdivided into hard carbon black and soft carbon black. Hard carbon black, also known as tread carbon black, is used as the main reinforcing and filling material for tires. With its excellent chemical properties, it can significantly improve the strength, tear resistance and wear resistance of the tread compound, and is mostly used in tire tread compounds. Soft carbon black, also known as carcass carbon black, can improve the viscoelasticity and flex resistance of the rubber compound in addition to the reinforcing effect, and is mostly used in tire sidewall and inner tube compounds.
　　The carbon black for tires produced by the company mainly includes 7 series and 12 models of products. The relevant product models, product performance and application fields are listed as follows:

Category	Series	Category code	Application characteristics	Main uses
Hard carbon black	N100 Series	N115	High reinforcement, super wear resistance	Tire tread compound
	N100 Series	N134	High reinforcement, super wear resistance, high modulus	Tire tread compound
	N200 Series	N220	High reinforcement, good tear resistance, excellent processability	Tire tread compound, carcass compound
	N200 Series	N234	High reinforcement, super wear resistance, high modulus	Tire tread compound, carcass compound
	N300 Series	N326	Medium reinforcement, low modulus, high elongation, good flex resistance	Tire carcass compound
		N330	Medium-high reinforcement, good processability	Tire tread compound, carcass compound
		N339	Medium-high reinforcement, high modulus, good wear resistance
		N375	Medium-high reinforcement, high modulus, good wear resistance
	LK Series	LK8201	High activity, high reinforcement, super wear resistance	Green tire tread compound
Soft carbon black	N500 Series	N550	Medium reinforcement, good processability, smooth surface of extruded rubber compound	Tire carcass compound, inner tube
	N600 Series	N660	Medium reinforcement, low heat generation, good flex resistance
	N700 Series	N774	Good elasticity, low compression set, low heat generation

　　② Carbon black for industrial rubber products
　　Carbon black for industrial rubber products has the characteristics of low impurity content, low sieve residue, high purity, high structure, and good dispersion, which makes it have high surface finish, no defects, good elasticity, small compression deformation, and excellent processability. Its main uses are sealing strips, sealing rings, rubber tubes, tape, shock-absorbing pads, etc. High-end environmentally friendly rubber products require lower PAHs (polycyclic aromatic hydrocarbons) and RoHS (heavy metals) content in carbon black.
The carbon black for industrial rubber products produced by the company mainly includes 6 series and 7 models of products. The relevant product models, product performance and application fields are listed as follows:

Category	Series	Category code	Application characteristics	Main uses
Special carbon black for rubber products	N200 Series	N220	High reinforcement, high modulus, good blackness	Rubber tubes, conveyor belts, molded products
	N300 Series	N330	Good reinforcement, high modulus, good blackness	Rubber tubes, conveyor belts, molded products
	N500 Series	N550	Medium reinforcement, good extrusion, small die swell, smooth product surface	Sealing strips, rubber tubes, conveyor belts, molded products
	N600 Series	N660	Good fatigue resistance, low heat generation	Rubber tubes, conveyor belts, molded products
	N700 Series	N774	Good processability, good elasticity, low compression set, low heat generation	Rubber tubes, molded products
	LK Series	LK5050	High purity, environmentally friendly, smooth product surface, good processability	Sealing strips, rubber tubes, molded products
	LK Series	LK5000	Good fluidity, good elasticity, small die swell, high surface finish	Sealing strips, foam glue, corner glue
