PVC material limitation of reason and influence of additives such as plasticizers, PVC cable insulation material is a certain limit. 1. The powder particles are too coarse. Cable compound powdered additives is generally used to go through the grind before, the easy way, or if some mechanical failure, resulting powdery substance is too coarse particles are added Weifang PVC flame retardant cable insulation would adversely affect . 2. colorants heavy metals. Many pigments are some of the heavy metal salts flame retardant PVC, these heavy metal ions increase the conductivity of the cable material, reducing its insulation properties. So cable paint choice is very important. Brittle cable problems, general and PVC resin type, plasticizers, lubricants, fillers, etc. For the formulation components. If you use the high PVC resin models, due to the PVC molecular chain is short, make the cable will be biased crisp performance. Add a small amount of plasticizer, cable rigid, sometimes biased crisp feel. Add more because of the filler is too large, and the performance degradation caused by cable flame retardant PVC manufacturer, strength is not good. Lubricant is another focus, if the external lubrication excessive, often caused by poor plastics (plastics plastics poor low temperature is another main reason), then the cable will be obvious strength is not good, brittle hair.
