Low-temperature anti-aging PVC film came out in Jiangsu

Since 2004, Jiangsu Shuangfa Plastic Products Co., Ltd. has been designated as a manufacturer of plastic products for the province's salt industry. He took advantage of this advantage, focused on the development of new products for salt films, and successfully developed medium and low-grade brine retort caps suitable for low temperature conditions. With PVC salt film products.

The company's scientific and technical personnel regard the salt film's resistance to low temperature and resistance to fresh water as the focus of the research, aiming at the technical problems of hard, brittle, easily damaged, and fast aging in low-concentration brines when the temperature of sub-zero temperature of PVC salt film products is low. Based on the formulation, new types of plasticizers and anti-aging agents that are not easy to be extracted by light, heat, oxygen, and fresh water aging, low temperature resistance are introduced, and reasonable and scientific adjustments are made to optimize the synergy between materials. The new salt film products have been tested in the laboratory. When the temperature is -5°C, the longitudinal and transverse elongation rate is 20% higher than that of the normal salt film. The cold resistance coefficient is significantly improved. The salt film has a longer life than the ordinary salt film in the use of middle and low-grade brine caps. Extended for more than 2 years.

At present, this product has been widely applied in some salt fields in Jiangsu, and its superior performance is also particularly suitable for use in salt fields in cold regions of northern China, and has broad application prospects.
