ETFE, or ethylene-tetrafluoroethylene copolymer, has a molecular structure consisting of linear polymer chains formed by the polymerization of ethylene and tetrafluoroethylene monomers. In this structure, the strong electronegativity of fluorine atoms gives the molecular chain excellent stability, while the introduction of ethylene units endows the material with a certain degree of flexibility, providing ETFE powder with unique fundamental characteristics for coating applications.

PTFE is a non-metallic crystalline polymer and an important specialty engineering plastic. It possesses excellent thermal and chemical stability, strong corrosion resistance, can withstand almost all strong acids, strong oxidizing agents, reducing agents, and organic solvents. It also has a wide operating temperature range.

Due to its excellent chemical resistance, high and low temperature stability, and low coefficient of friction,PTFE material is widely used in various fields such as industrial manufacturing, electronics, aerospace and others. Let’s learn its main molded products and manufacturing processes.

ETFE resin is the "specialty elite" of the plastics industry---resistant to high temperatures, corrosion and extreme environments, it is used in everything from small precision components to large-scale Olympic venues. With its unique advantages of transparency ,mechanical strength and radiation resistance, ETFE has become a "star material" in construction, new energy, aerospace and other fields.

PFA, full named polytetrafluoroethylene-perfluoroalkyl vinyl ether, which is a high-performance fluoroplastic that demonstrates unique value in numerous industrial fields. The excellent chemical stability, high-temperature resistance, corrosion resistance, and low coefficient of friction make it a focal point in the field of materials science.

PVDF is a homopolymer of vinylidene fluoride or a copolymer of vinylidene fluoride with other fluorinated vinyl monomers. It is a high-performance fluoropolymer material second only to polytetrafluoroethylene (PTFE), and is widely used in photovoltaic backsheets, aerospace, robotics, optical instruments, industry and etc. Among them,PVDF Material for Photovoltaic Backsheets application is particularly prominent.

Rely on high performance,fluoropolymer coating is used across various demanding environments. Today let’s know the different fluoropolymer resin coating properties and process.

On June 5, 2024, the U.S. Environmental Protection Agency (EPA) proposed restricting the use of NMP. NMP is used as a solvent in the production of lithium-ion battery cathode electrodes and their raw materials (such as graphene conductive slurry, solid electrolyte slurry etc) ,which fuse the required substances together, allowing the raw materials to perform at their best. If the use of NMP is banned in lithium-ion battery production, then PTFE dry electrode technology is highly likely to be the replacement.

PCTFE resin is a key product of our national strategic emerging industries. In the past, our country relied heavily on import.But in recent years,our domestic enterprises have successfully achieved PCTFE resin made in China, filling the gap in the domestic field of ultra-low temperature corrosion-resistant materials, solving the problem of tensile fracture of fluoropolymers at low temperatures, and promoting the domestic substitution process of key materials.
