    Conductive pS plastic

    Time: 2019-03-18 18:30 Author: admin Hits: Times

    Carbon black for rubber is mainly abrasion-resistant carbon black, which can effectively improve the abrasion resistance of rubber tires. Carbon black is most widely used in plastics due to its abundant sources, high purity, and small particle size. Can black masterbatches be used in conductive pS plastics?

    A carrier is a substance that carries carbon black. Whatever raw materials are used in plastic products, the carrier is used. The black masterbatch manufactured in this way has good compatibility with plastic raw materials.

    The specific gravity of carbon black is about 2g / cm. Due to the small particle size of carbon black, the performance density is very small, it looks fluffy, and it seems very light. For smooth processing, carbon black must first be wetted.

    Black masterbatches also require processing aids. Smooth processing requires proper selection of antioxidants, internal lubricants, external lubricants, modifiers and antistatic agents.

    Processing methods have an effect on masterbatch performance. The mixing method improves the carrying capacity of the carrier for carbon black, and at the same time, carbon black can enter the carrier more uniformly. Taking advantage of the mechanical kneading of the internal mixer, crushing the agglomerated particles, greatly reducing the agglomerated particle size of the carbon black particles, and the uniformity of the carbon black particle size in the mother particle and its distribution cannot be replaced by the other two methods. The performance of conductive pS plastic is determined by the raw materials of processing.
