PTFE high-efficiency filter material has small pore size
Polytetrafluoroethylene high-efficiency filter material, as one of the most popular filter materials in today’s era, has effectively solved many problems in people’s lives. Today we will fully understand this material.
The raw materials of masks are mainly composed of spunbond nonwoven materials, meltblown nonwoven materials, air-through nonwovens, needle-punched nonwoven materials, as well as accessories such as ear straps and nose bridge strips.
Among them, melt-blown nonwoven materials, as the core filter layer of masks, have the characteristics of fine fiber fineness (average fiber diameter 2~4 μm), small pore size, large specific surface area, and high porosity, making melt-blown nonwoven materials unique Certain breathability and excellent filtration function.
Polytetrafluoroethylene high-efficiency filter material refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, there are up to hundreds of millions of micropores per square centimeter, and the filtration level can reach H13 -U16, can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
The polytetrafluoroethylene high-efficiency filter materials 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.
