So far, the United States, Japan, Germany, Switzerland and other countries have conducted research on PTFE biaxially stretched films, and have obtained microporous materials of polytetrafluoroethylene, which has provided great opportunities for the development of the world economy. power.
We all know that clean rooms (CLEANROOM) need to use many filtration equipment when constructing purification projects, and the cores of these filtration equipment are almost all made of ptfe biaxially stretched membrane. Tetrafluoroethylene is a polymer compound of tetrafluoroethylene. It is one of the materials with the best corrosion resistance in the world today. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it can withstand all other chemical reactions and is insoluble in strong acids, Strong bases and organic solutions do not change in boiling nitrohydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
The biaxial stretching process of the polytetrafluoroethylene film gives the film good void characteristics. After the film is stretched in different directions, the structure of the micropores and agglomerations of the film changes, and at the same time the mechanical properties of the film are improved. Has anisotropic properties.
It is a fluorine material film manufacturer integrating production, sales and customization.
