1.Is the PTFE membrane organic?
First of all, we need to know that the presence of C in the chemical formula of an object does not mean that it must be organic, because CO also contains C, but on the contrary, CO is the final product of organic combustion, and CO cannot burn. But polytetrafluoroethylene can react with oxygen under certain conditions, and the final product produced is CO, so it must be organic. Thus, PTFE membrane is an organic material and organic membrane.

2.How high temperature can the PTFE membrane withstand?
Polytetrafluoroethylene membrane can maintain excellent mechanical properties in a wide temperature range of -196～260℃. One of the characteristics of perfluorocarbon polymer is that it is not brittle at low temperature.

3. PTFE membrane mask
Polytetrafluoroethylene mask membrane has the characteristics of high porosity and strong hydrophobic performance. It has good adsorption performance, efficient removal rate and high flow rate. The pore size of the mask made of PTFE membrane can intercept large particles in the air, and can also absorb PM2.5 by using the electrostatic effect, effectively block the PM2.5 in the air, and effectively reduce the concentration and use of bacteria and viruses in the air with longer life. Masks made with it can better block fine dust from entering the filter material, realize surface filtration, and make the dust removal efficiency reach 99.9%~99.999%, and even have a higher dust removal efficiency for fine particles of PM2.5~PM10. A level close to "zero emission" can be achieved.

4.The use of PTFE membrane
Polytetrafluoroethylene membrane is a breathable insulation membrane suitable for the insulation of capacitor dielectrics, special cables, wire insulation, electrical and instrument insulation and sealing gaskets. It can also be used as non-stick tape, sealing tape, mold release and heat insulation materials. It is widely used in light industry, military industry, aerospace, oil field and other fields.
With the continuous development of material application technology, the three major shortcomings of polytetrafluoroethylene membrane (PTFE) materials: cold flow, difficult to weld, and difficult to melt processability are gradually being overcome, making it have a broader application prospect in optics, electronics, medicine, petrochemical oil transportation and anti-seepage fields.
