luoropolymer materials are obtained through homopolymerization or copolymerization of monomers containing fluorine atoms. Due to the extremely short C-F bonds and extremely high bond energy, fluoropolymer materials have excellent physical and chemical properties compared to ordinary polymer products. Performance, material structure is complex, diverse, and widely used.
Fluoropolymers are mainly divided into two categories: fluororesin and fluororubber. The monomers and production processes required for the two are similar. Among them, due to its special structure, fluororesin has excellent performance in many aspects such as heat resistance, acid resistance, alkali resistance, and drug resistance. Common fluororesin varieties mainly include polyvinylidene fluoride (PVDF) , polytetrafluoroethylene (PTFE), polyperfluoroethylene-propylene (FEP), fusible polytetrafluoroethylene (PFA), ethylene-tetrafluoroethylene copolymer (ETFE), etc.
(1) Polyvinylidene fluoride (PVDF)

Since the 1970s, PVDF has ranked second in production and sales in the fluorine- containing polymer materials industry due to its excellent comprehensive properties. The operating temperature range of polyvinylidene fluoride is -60℃-150℃. It has good resistance to chemical corrosion, hydrolysis and ultraviolet resistance, and its mechanical strength is better than other fluororesins.
The downstream applications of domestic polyvinylidene fluoride products are mainly in the coating industry. PVDF has excellent chemical resistance and electrical insulation. As a binder for lithium battery materials such as cathode materials and separators, PVDF is one of the indispensable key materials in the lithium battery industry chain.
The increasingly stringent environmental protection requirements of countries around the world have promoted the development of the two main application areas of polyvinylidene fluoride (PVDF), including new energy and environmental protection. Lithium batteries, as the largest application direction of polyvinylidene fluoride (PVDF), are expected to expand in 2025. Maintain a compound growth rate of 30%.
At the same time, the vigorous development of the integrated circuit industry will also promote the rapid development of polyvinylidene fluoride (PVDF) products, which is expected to reach a market size of approximately 40,000 tons/year by 2025. Affected by the rapid development of the above fields, the comprehensive market size of PVDF will reach more than 150,000 tons in 2025.
(2)PTFE
PTFE is a polymer polymerized from tetrafluoroethylene monomer. It is a transparent or opaque wax similar to polyethylene. It is one of the best corrosion-resistant materials in the world today. Except for molten metal sodium and liquid In addition to fluorine, it is resistant to all other chemicals. In addition, PTFE is acid and alkali resistant, has excellent temperature resistance, low friction coefficient, low dielectric loss, small dielectric constant, good anti-sticking performance, and strong biological adaptability. It is known as “King of Plastic.
(3)FEP
FEP is a modified material of PTFE, which is copolymerized with tetrafluoroethylene and hexafluoropropylene. FEP has the characteristics of insulation, flame retardancy and high temperature resistance. It is often used as the insulation layer of various cables and wires in the electronic and electrical industry.
At present, the production capacity of domestic manufacturers is mainly concentrated in polyperfluoroethylene and propylene molding materials, general extrusion plastics and concentrates. The main application areas are wires for lighting and home appliances, chemical equipment linings, and surface anticorrosion. In high-end polyperfluoroethylene and propylene, There is still a serious lack of modification design of polymer molecular segments and the production of high-purity polyperfluoroethylene-propylene polymer materials. In order to meet the requirements of high-end fields such as communications, electronics, and new energy, product quality improvement will be a later development trend.
