What is the cause of the problem of the air hole in the cable material?

There are two main reasons for the problem of air hole in the cable material. First, the moisture in the raw material is high. It is possible that the raw material with excessive moisture is PVC resin, plasticizer, filler and stabilizer. Due to the large amount of PVC resin and filler, the PVC resin and filler should be As the focus of the inspection. This condition is generally manifested in the kneading process and the vacuuming of the extruder. Second, because the stability of the formulation system is poor or the residence time of the material is too long, the material is decomposed and the pores appear. When this problem is serious, it is usually accompanied by a change in color.
