Performance of polymer protective film

The wholesale market of polymer protective film has always been very good. This is because the protective film has good performance and is very helpful for our use. The first is permeability. The permeability of the membrane is closely related to the temperature, the thickness of the membrane, the preparation process conditions, the chemical composition and the microstructure of the membrane. The second is membrane distillation. Membrane distillation is a separation process powered by vapor pressure difference. Its characteristic is that it can handle high-concentration solutions at a suitable temperature under normal pressure. In addition, there are electrical properties. Most polymers are non-conductive materials, so they can be used as insulating materials in the electrical industry. The performance of the polymer protective film is the above. When we use it, we can determine the use environment based on its characteristics.
