Plastic treatment: the water absorption rate of PC plastic raw materials is large, and it must be preheated and dried before processing. The pure PC should be dried at 120 ℃ and the modified PC should be dried at 110 ℃ for more than 4 hours. The drying time should not exceed 10 hours. Generally, the air extrusion method can be used to judge whether the drying is sufficient. The proportion of recycled materials can reach 20%. In some cases, recycled materials can be used, and the actual amount depends on the quality requirements of the product. The recycled materials should not be mixed with different color masterbatch at the same time, otherwise the properties of the finished product will be seriously damaged.

PC属自熄性材料; 对光稳定，但不耐紫外光，耐候性好; 耐油、耐酸、不耐强碱、氧化性酸及胺、酮类，溶于氯化烃类和芳香族溶剂，长期在水中易引起水解和开裂，缺点是因抗疲劳强度差，容易产生应力开裂，抗溶剂性差，耐磨性欠佳
