In recent years, as the energy shortage problem worldwide has become more and more serious, new fuel cells have made great progress and have been practically used in different fields. Then you know that fuel cells are indispensable What is a material? It is a polytetrafluoroethylene proton membrane. Let’s learn more about it.
PEM, ProtonExchangeMembraneorPolymerElectrolyteMembrane, proton exchange membrane, also known as polymer electrolyte film.
As can be seen from the name, its main function is to transfer protons. In addition, it also needs to isolate the fuel and oxidant to prevent direct chemical reactions caused by penetration.
PTFE proton membrane is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics currently.
It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The surface of the product is glossy.
It is a fluorine material film manufacturer integrating production, sales and customization.
The company has advanced polytetrafluoroethylene proton membrane production lines and composite production lines.
The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
