Application areas of PTFE bubble point membrane
Polytetrafluoroethylene bubble point film is generally made of polytetrafluoroethylene (ptfe) suspended powder as raw material, which is expanded and stretched to form a microporous film.
Bubble point film has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is coated on various fabrics using a special process and base material, it can become a new type of filter material.
Polytetrafluoroethylene bubble point film 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%, and there are up to hundreds of millions of micropores per square centimeter.
The product has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
In industries such as pharmaceuticals and electronic semiconductor production, there are higher cleanliness requirements for air. Semiconductor production requirements are that there should be no more than 1 particle per cubic foot of air, while in ordinary environments, there are 500,000 particles per cubic foot of air. above particles.
Therefore, it also has good filterability for special gases with high temperature, high humidity, high corrosion and organic liquids.
So PTFE bubble film is widely used in medical, electronics, precision machinery and other industries.
It is a ptfe environmentally friendly filter material manufacturer that specializes in R&D, customization, production and sales.
