Development of fluoroplastics 2. It has been widely used in aerospace, atomic energy, electronics, electrical, chemical, machinery, construction, textile, pharmaceutical and other industries. 

The products that have been industrialized and sold on the market include polytetrafluoroethylene (PTFE), Polyvinylidene fluoride (PVDF), ethylene-tetrafluoroethylene copolymer (ETFE), ethylene-chlorotrifluoroethylene copolymer (ECTFE), polyvinyl fluoride (PVF), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer There are about 100 brands of more than ten varieties, including PFA, tetrafluoroethylene-hexafluoropropylene copolymer (also known as polyperfluoroethylene propylene FEP), and polychlorotrifluoroethylene (PCTFE). 

 In the 1980s, on this basis, my country's fluoroplastic processing enterprises (mainly township enterprises) were established, especially in Jiangsu and Zhejiang provinces, which greatly promoted the growth of my country's fluoroplastics processing industry. Sector, and increasingly penetrate into people’s daily lives. In recent years, China's sustained and rapid economic growth has provided a broad market space for fluoroplastic products.1 Historical review of fluoroplastic molding process research and product processing in China The history of the development of the fluoroplastics processing industry in China is a typical epitome of the Shanghai Plastics Research Institute. S.. 

It was the earliest established research institute mainly engaged in the research of fluoroplastics molding process in China. Some products have replaced imports, and some A large number of products go to the international market. In the late decade, a series of process technologies such as compression molding, push molding, blow molding, injection molding, (spiral) extrusion molding, dipping, coating, and surface treatment of fluoroplastics have been researched, and corresponding technologies have been established. 

It is difficult to replace other conventional plastics, so its economic benefits are much higher than conventional plastics. Although processing is relatively difficult, they have high thermal stability, low dielectric constant, low moisture absorption, low flammability, low surface energy, excellent weather resistance and excellent chemical resistance. 

Since Plunkett synthesized polytetrafluoroethylene, the development, production, processing and application of fluoroplastics have been greatly developed, so there are many varieties. Since 1938, American scientist R. Test, test methods, and theoretical basis BBQ grill mat Manufacturers for the design of molds and non-standard molding equipment. Fluoroplastics are polymer materials with excellent performance.1 Introduction Fluoroplastics are an important type of plastics with excellent performance. It was established in 1958 and was formally established in 1963
