Mechanically stretching eptfe proton exchange membrane
In order to obtain stable and cheap fuel cells, proton exchange membranes are the biggest bottleneck and must be broken through in the future In the field, what we are going to introduce today is the eptfe proton exchange membrane. Let us take a closer look at it.
According to the fluorine content, proton exchange membranes can be divided into perfluorinated proton exchange membranes, partially fluorinated polymer proton exchange membranes, non-fluorinated polymer proton exchange membranes, and composite proton exchange membranes. exchange membrane. Among them, because the main chain of the perfluorosulfonic acid resin molecule has a polytetrafluoroethylene (PTFE) structure, it brings excellent thermal stability, chemical stability and high mechanical strength;
eptfe proton exchange The membrane is mainly made by mechanical stretching of PTFE material. PTFE is a highly crystalline polymer polymerized with tetrafluoroethylene as a monomer. It is a white waxy thermoplastic similar to polyethylene (PE). It has excellent high temperature resistance and low temperature resistance, with a melting point of 327 degrees Celsius and a decomposition temperature of 415 degrees Celsius. It can be used for a long time in the range of 200 to 260 degrees Celsius. At the same time, the material has strong hydrophobicity, non-adhesion, corrosion resistance, thermal stability and good mechanical properties. Therefore, it can be washed with water to restore its performance and achieve repeated use, greatly extending its service life and saving costs.
It is a manufacturer of eptfe proton exchange membrane materials that specializes in R&D, production and sales. Our company is different from other manufacturers. Our company can according to the user’s requirements. By optimizing the key technical parameters of speed ratio, pressure ratio, operating temperature and other parameters, online control of air permeability, thickness and void ratio can be achieved based on the ratio and pore-forming medium to meet your different requirements. Interested parties can enter the store for consultation.
