![]() ![]() N550 is easy to disperse, resulting in high enduring property, high extrusion rate. Thermal black and channel are made from natural gas feedstock. Most black today is derived from controlled burning of petroleum oil. Carbon black is a spherical particle of carbon formed by burning an aromatic feedstock. It's better to mix with N660 when the N550 is used in butyl rubber (PIBI) inner tube. Carbon black N550 is suitable for natural rubber and synthetic rubbers. Carbon is nature’s most flexible element it comes in pure forms that can radically differ like diamonds and graphite. Carbon Black N550 is mainly used in tire cord layer, tire side, extrusion and calendering products. This is a change of 2.48 from last month and -12.18 from one year ago. N550 fits for nature rubber and all kinds of compound rubbers, easy dispersion, could provide rubber well inflexibility, fast extrusion, and smooth surface after extrusion with good reinforcing intensity, elasticity, and recovering intensity. Product Description: We are a carbon black Group company and have three factories in Shandong and Shanxi province of China. Carbon Black N550 is a kind of rubber carbon black, suitable for natural rubber and various synthetic rubber, easy to disperse, can give the rubber material high stiffness. US Producer Price Index: Chemicals and Allied Products: Carbon Black is at a current level of 600.66, up from 586.15 last month and down from 683.96 one year ago. Carbon Black N550 is recommended to be used in cord layer of tires, sidewall of tires, the rubber material for extrusion or calendered goods. STERLING SO conforms to ASTM N550 carbon black target values.
