Welcome to inquire! Contact: the Wu Hu. Cable surface roughness surface roughness are two problems, one is flame retardant PVC knots, one is pitting. Lump mainly by a number of non-uniform dispersion of the mixed powder aggregate, the extrusion process can not plasticized, plasticized PVC material is extruded from a die coated together Shandong PVC flame retardant, and is formed in the cable compound a. Fish eyes and not fully absorb plasticizer PVC resin particles mentioned earlier can also cause lumps phenomenon, but generally is relatively small. PVC cable insulation is a certain limit. For ordinary PVC flame retardant cable materials for Weifang, if insulation obvious bias, have the following main reasons: the high side of impurities. Impurities mixed cable will adversely affect too many impurities can cause insulation problems. These impurities may be derived from a variety of PVC resins and additives may also be derived from the mixing and feeding links.
