The new process carbon black is a new generation of carbon black which is improved on the basis of the traditional carbon black manufacturing process. They first appeared in the early 1970s, when the first variety introduced was N339, a high-structure, high-wear carbon black produced by a new process.
Performance characteristics
The reason why the new process carbon black can be promoted faster is due to the following reasons:
1. Performance parameters have an advantage. Compared with the corresponding traditional carbon black varieties, the new process carbon black has the characteristics of low specific surface area, small particle size, narrow particle size distribution, high structure and small roughness (smoothness), so it can give rubber better wear resistance and Higher modulus of elongation. This is also related to its surface activity, which is easily related to the formation of bonded rubber between rubber.
2. The above performance parameters can also provide better processing performance for rubber tape, especially low heat generation, small shrinkage deformation of unvulcanized rubber, and smooth surface of extruded rubber.
3. price advantage.
Due to the high yield of the new process carbon black, its price is relatively lower than the corresponding conventional carbon black.
Due to the advantages of the above three aspects, the new process carbon black is increasingly welcomed by users. The most suitable application is the rubber tubing manufacturing industry, because the smooth surface and dimensional stability are the key to rubber extrusion, and the new process produces carbon black just right. Can meet these requirements.
Moreover, the new process carbon black can be used for rubber tubes and other extruded products that use the extrusion process.
In addition, it is worth mentioning that the new process carbon black has the characteristics of strong tinting strength compared with the conventional carbon black of the same grade. Therefore, for the black rubber tube, they have a good coloring effect.
