The ptfe reusable mask filter membrane has very excellent tensile properties. It can be formed and rolled up even when stretched hundreds of times in both vertical and horizontal directions. Moreover, the minimum thickness of the material can be less than 1um, and it can be used with very low resistance. Higher efficiency can be obtained at the same time.
In fact, the uniformity of filter material rolls, including transverse uniformity and longitudinal uniformity, is an important indicator that determines the level of filter material production.
This is related to the production equipment, the production process, the responsibility of the production personnel, and even the production environment and temperature.
Generally speaking, the deviation of residual and resistance is controlled at ±20%, which is considered a product with very good stability.
The dust removal efficiency of ptfe reusable mask filter membrane 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 permeability, breathability and waterproof properties.
The melting point is 164~170℃, and the products can be sterilized at temperatures above 100℃.
The ptfe reusable mask filter membranes produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop, ensuring the production quality of ptfe membranes ;Using production and testing instruments imported from the United States to test the quality of PTFE film, and passing international SGS testing and certification, as well as ISI testing and certification.
