Cable as soft products, a large number of plasticizers, so generally do not pay attention when formulation lubricants, will use some low-grade lubricant company Weifang retardant PVC, these low-grade lubricant low melting point, a lot of content out of the late Yi Weifang evaporate retardant PVC, can not be excluded at this time, had been molten material wrapped folder before the trip, due to the proportion of light gases will escape to the surface as possible, occupy a certain space, and the material is forced transported together, from die immediately after it came out into the air PVC flame retardant, but in the cable but left little trace. 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 Weifang retardant PVC brand, resulting powdery substance is too coarse particles are added, would produce cable insulation material adverse affected. 2. colorants heavy metals. Many pigments are some of the heavy metal salts, these heavy metal ions increase the conductivity of the cable material, reducing its insulation properties. So cable paint choice is very important.
