In recent years, various ptfe products and derivatives produced by ptfe microporous membrane manufacturer have unknowingly entered people’s lives. Zhonglai, as a new functional material, ptfe has many excellent and outstanding properties among many materials.
The molding process of ePTFE is to extrude the paste to form a preform arranged longitudinally into fibers. After drying, the auxiliary PTFE is removed. After extrusion, high-speed stretching is performed at a temperature lower than the melting point of PTFE (327°C), and then the PTFE semi-finished product in the stretched state is heat treated at the temperature of the melting point of the paste to obtain a porosity of 40%-97%. Expanded PTFE tubes, membranes, rods, etc. This method is called stretch molding method, and the raw material needs to be ultra-high molecular weight dispersed polytetrafluoroethylene resin.
ptfe microporous film manufacturerThe microporous film is prepared by a special biaxial stretching process. Polytetrafluoroethylene microporous The membrane has a node-fine fiber structure, forming hundreds of millions of micropores per unit area, which can intercept dust in the air very well. It is very suitable for air purification fields, such as vacuum cleaner applications. The air filtration membrane has high breathability and high interception. The efficiency enables the vacuum cleaner to not only intercept dust particles with an accuracy of H14 level (99.995%) or above, but also allows the vacuum cleaner to maintain low energy consumption, and the material can be washed to restore performance and be reused.
