Not many people know about conductive carbon black masterbatch, and it is very unfamiliar to some people. Here, I will explain the relevant knowledge points of conductive carbon black masterbatch, so that everyone can further understand the processing of conductive carbon black masterbatch.
What is conductive carbon black masterbatch
Conductive carbon black masterbatch is to condense conductive carbon black into conductive carbon black masterbatch by masterbatch method, add HIPS raw material to dilute and then granulate.
Advantages of conductive carbon black masterbatch processing
The performance and toughness of the conductive carbon black masterbatch made in this way are much better than the direct addition of granulation. According to relevant sources, the main reason is that the conductive network is formed by the masterbatch method, so the effect is good.
The reason why the conductive carbon black masterbatch method is better than the general granulation effect
Injection molding will destroy the original conductive channel, and the carbon black will agglomerate again during the screw mixing process, so the compression molding method has higher conductivity than injection molding. As for the effect of one-step granulation is worse than that of the masterbatch method, fundamentally speaking, it is still a problem of dispersion. The two-step method is better than the one-step method, but the three-step granulation is not necessarily better than the two-step method, due to the difference with the equipment. The mixing efficiency is related to the formula. In other words, the WP twin-screw may be used in one step to achieve the effect of the domestic equipment in two steps. The new equipment is better than the old equipment.
Conductive carbon black masterbatch price
Conductive carbon black masterbatch is produced by the masterbatch method, and the masterbatch method has high requirements for equipment, resulting in a higher price of conductive carbon black masterbatch, and the price will not be too high.
Superconducting carbon black masterbatch density
The greater the filling amount of carbon black, the greater the density of carbon black particles or aggregates of carbon black particles in a dispersed state, the smaller the average distance between particles, and the higher the probability of mutual contact. Carbon black particles or aggregates of carbon black particles The more conductive paths are formed.
Types of conductive carbon black masterbatch
According to the application, conductive carbon black masterbatch can be divided into: conductive carbon black masterbatch for fiber, superconductive carbon black masterbatch for ABS and other conductive carbon black masterbatch.
