由于不同批次聚丙烯(PP)回收料中含有不同的着色剂和成核剂,使得PP的回收越来越困难。着色剂和成核剂的差别会影响回收PP的成型收缩率,其加工制品易发生
Due to different batches of polypropylene (PP) recycled materials contain different colorants and nucleating agents, making the recovery of PP more and more difficult. The difference between the colorant and the nucleating agent will affect the molding shrinkage rate of recycled PP, the processing of products prone to
