Polytetrafluoroethylene mask cloth is made of polytetrafluoroethylene as raw material, which is expanded into a microporous film, and then This film is coated on various fabrics or paper substrates using a special process, making it a new type of filter material. It has the advantages of traditional filter materials. From a production point of view, its technical requirements are much higher than those of ordinary hydrophobic materials. From a quality point of view, it also has functional characteristics that other hydrophobic materials do not have.
Polytetrafluoroethylene mask clothThe filtration principle is surface filtration , with small filtration resistance, it can block harmful gases in the air from the outside and ensure that they are not inhaled by the human body. By controlling the pore size of this membrane between 0.2 and 3 μm, it can well intercept fine dust with a small diameter. Widely used in kn95 masks, disposable masks, etc.
PTFE nano mask cloth dust removal efficiency can reach more than 99.9995%. The minimum pore size of the film can reach 0.1um, which can capture most solid particles and liquid droplets. Since the pore size of the mask film is much larger than water vapor molecules, and polytetrafluoroethylene is a hydrophobic material, water droplets cannot penetrate the micropores, so it has good Moisture permeable, breathable and waterproof. The melting point is 164~170℃, and the products can be sterilized at temperatures above 100℃.
It is an environmentally friendly material manufacturer specializing in R&D, production and sales of polytetrafluoroethylene mask cloth. Our company is different from other manufacturers. Our company can according to the user’s requirements.
