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 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.

Carbon Black N375 Other Name:High abrasion furnace black-high structure （New technology）；HAF-HS（New technology） N375 is another grade of high abrasion furnace black with high structure (new technology). Its structure is a little lower than N339, and its properties are similar as N339. Usage: The usage and function of N375 is similar as carbon black N339 although the structure and heat-up is a little lower than N339. Application: The application of   carbon black N375   is similar as N339, mainly used in the tread compounds of passenger tire, truck tire and cross-country tire. It is also used in coating compounds of conveyor belt.   Beilum Carbon Chemical Limited Add: Shizhong Industry Area,Zaozhuang City,277101,Shandong,China.
