China Carbon Black Supplier - Beilum Carbon - www.beilum.com

  The main use of carbon black is in tires and rubber industry. The amount of Rubber carbon black used in tires accounts for more than 80% of the entire rubber industry. Carbon black used in rubber products other than tires accounts for 20% of the carbon black used in rubber.  Carbon Black N330 Tire rubber | The role of carbon black in rubber: 1. Play a reinforcing role to increase the wear resistance and service life of rubber products. 2. Use filler to save costs. Tire rubber | Classification of carbon black for rubber Carbon black for rubber mainly depends on the physical properties, wear resistance and tensile properties of carbon black. Currently, the common carbon black for rubber is Carbon Black N220,  Carbon Black N330 , Carbon Black N550, Carbon Black N660, Carbon Black N774 and other series. Tire rubber | The role of different types of carbon black in rubber: High wear resistance: Carbon Black N110, Carbon Black N220,  Carbon Black N330 , N339, etc. Reinforced types: Carbon B

  The reinforcing effect of carbon black is mainly that the addition of carbon black changes the structure of the rubber and produces a C-phase structure. In vulcanized rubber, if the carbon black is well dispersed, and a C-phase structure is formed on the surface of each carbon black particle , Phase C plays a skeleton role to connect phase A and phase B. Forming an overall network of rubber macromolecules and fillers, changing the structure of the vulcanized rubber, thus improving the physical and mechanical properties of the vulcanized rubber. Reinforcement mechanism of  carbon black  Surface adsorption layer theory This theory believes that Black carbon and rubber generate a microscopic multi-phase inhomogeneous structure, which is a reinforcing mechanism of composite materials. Nuclear magnetic resonance studies have confirmed that there is an adsorption layer composed of two types of rubber macromolecules on the surface of carbon black. The inner layer of about 0.5nm close to the

Carbon Black N234   Other Name:Intermediate Super Abrasion Furnace Black-high structure (New technology); ISAF-HS (New technology) N234, compared to other grades of N220 series, has higher structure, higher abrasion. Usage and Function: The compound filled with Carbon Black N234 has better abrasion than those with N220, N242 and N339. Its abrasion is about 10% higher than those of compounds with N220. Especially in the rigorous conditions, it shows very good abrasion performance. The process performance of the N234 compounds is good too. The surface is smooth, suitable for various compounds. The deficiency of the N234 compounds is its high heat-up and high hysteresis loss. Application: N234   is used in the tread compounds of high speed tire and high performance rubber products.   Beilum Carbon Chemical Limited Add: Shizhong Industry Area,Zaozhuang City,277101,Shandong,China.

  Carbon Black N220 Other Name:Intermediate Super Abrasion Furnace Black; ISAF N220 with high re-enforcement property is a widely used furnace black. It has high structure, and its abrasion is between those of super abrasion furnace black and high abrasion furnace black. Usage and Function: Carbon black N220 can be used in various rubber compounds. Compared to the compounds filled with carbon black N330, those with N220 has higher abrasion of 10%~20%, higher tensile strength and higher crack resistance, higher heat-up and hardness. The compound filled with N220 is conductive. Application: Carbon black N220  is used in tread compounds of truck tire, passenger tire and high strength high abrasion rubber products, such as high strength conveyor belt and industrial rubber articles etc. It is also used for Masterbatch, Paper, Printing system.

  Carbon Black N339   Other Name:High Abrasion Furnace Black-high Structure （New technology）；HAF-HS（New technology） Compared to N330, N339 has higher structure, smaller particles. The N339 compound has better abrasion and crack resistance than those of high abrasion furnace black –high structure (old technology) such as N347. Application: N339 is used in the tread compounds of passenger tire and truck tire, coating compounds of conveyor belt, hose and industrial compounds with high abrasion properties. It is also used in Printing Inks. Usage: The tread compound filled with N339 has similar re-inforcement, abrasion and crack resistance properties as those of  Carbon Black N220  compounds, and has good extrusion property, very suitable for butyl benzene rubber/ butyl rubber compound. The N339 compound has the highest rolling resistance among all the compounds with N330 series. Beilum Carbon Chemical Limited Add: Shizhong Industry Area,Zaozhuang City,277101,Shandong,China.
