Plasticizers and PVC resin compatibility is poor, such a high proportion of plasticizer, the precipitation problem is inevitable. Usually it comes down to the plasticizer here. In fact, PVC resin particle shape has a lot to do with this, if the particles are too tight, thick film, a plasticizer is not easy to enter into the particles, thus affecting the resin and plasticizer molecules "fit." 100gPVC resin plasticizer absorption of this performance only partially reacted resin can be used as a reference. But there are large differences in the actual situation. If it is due to the resin causes precipitation of generally rigid or plasticized material will appear bad phenomenon pvc flame retardant component, some small particles similar fish-eye-like substance. Shandong Antai New Material Technology Co., Ltd. Main PVC cable, welcomed the new and old customers to buy. My company provides products flame test analysis. Cause PVC material limitations and plasticizers and other additives influence, PVC cable insulation is a certain limit. 1. The powdery particles are too coarse. Cable compound powder additives are generally used to go through the grind before pvc flame retardant formulations, the easy way or if some mechanical failure, resulting powdery substance is too coarse particles are added, will produce cable insulation material adverse influences. 2. colorants heavy metals. Many pigments are some of the heavy metal salts, these metal ions will increase the conductivity of the cable, reducing its insulation. So cable pigment choice is very important.
