With the large-scale outbreak of COVID-19 around the world, disposable medical mask filter materials have become a powerful tool for epidemic prevention and control. It is an important raw material indispensable for making disposable masks.
The raw material of PTFE membrane is granular PTFE resin, which is a homopolymer of tetrafluoroethylene and cannot be processed by ordinary thermoplastic molding methods.
It is processed using principles similar to powder metallurgy, such as suspension method, dispersion method, liquid method and other polymerization methods.
There are many products of PTFE resin powder abroad, and there are also a small number of manufacturers in China.
Foreign manufacturers are represented by DuPont Company of the United States and Daikin Company of Japan.
The respiratory impedance of the filter material of disposable medical masks is only 60-70pa, while that of ordinary melt-blown non-woven masks is as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it must not be worn without it. Mask Vs.
The wearing comfort of a polytetrafluoroethylene film mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of film materials, they can give users a more comfortable breathing experience.
