Shandong Antai New Material Technology Co., Ltd. (www.antaitech.com) is specialized in the "fireproof material" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: the Wu Hu. Plasticizers and PVC resin compatibility is poor, the high proportion of such plasticizers, precipitation problem is inevitable. Usually attributed to the plasticizer here. In fact, PVC resin particle shape has a lot to do with this, if the particles are too tight PVC flame retardant coating is too thick, the 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 is a big difference and the actual situation. If it is due to the resin causes precipitation of Shandong PVC flame retardants, generally there will be more rigid material or plastics bad phenomenon, some small particles similar to the fish-eye-like substance. Cable problem rough surface rough surface at the two Weifang retardant PVC, one is 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 together coated flame retardant PVC manufacturer, and in the cable compound formation. Fish eyes and not fully absorb plasticizer PVC resin particles mentioned earlier can also cause lumps phenomenon, but generally is relatively small.
