UPVC pipes are widely used in urban water supply, drainage, construction water supply and drainage. All along, UPVC pipe fittings have been prepared by adding various additives and then granulated. The development of a pellet with good dispersion, uniform color, good processability, and direct injection molding into pipe fittings has become a desire of many pipe fitting manufacturers. . Shandong Chunchao Masterbatch Co., Ltd. has successfully developed for six months. The pellets use food grade PVC resin, non-toxic organic tin or calcium zinc composite stabilizer, no plasticizer, and good processing performance and thermal stability.
According to the monitoring by the Institute of Environmental Health Monitoring of the Chinese Academy of Preventive Medicine, 18 physical and chemical indicators are in line with the “Safety Evaluation Standards for Drinking Water Distribution Equipment and Protective Materials for Drinking Waterâ€. The pellets can be directly injected into UPVC pipe fittings, and the injection molding process of pelletizing and injection molding is ended, and the cost advantage is achieved. It is reported that Shandong Chunchao Masterbatch Co., Ltd. will form an annual production capacity of 6,000 tons.
Recently, water-repellent UPVC pipe fittings for environmental protection have been successfully developed by Shandong Chunchao Masterbatch Co., Ltd., and have been identified by the Science and Technology Department of Shandong Province to fill the gaps in the domestic market. The pellets can be directly injected into the pipe fittings, thus ending the first granulation and re-injection process. Tube injection molding process.
