Detailed Product Description

It is a kind of carbon black with higher structural character,the abrasion character of the rubber material using N234 is better than N220, N242, N339, and its abrasion character about 10% higher than N220. Especially used in high harsh condition, its advantage can be more obvious. Because the machining capability of this glue material is also better and the pressing outside is glazed. So it can be mainly used in high speed tire surface glue and high quality rubber products.
