In industrial production, especially in automated processes, problems such as damage or reduced efficiency of ptfe due to contact with water are often faced. Therefore, the hydrophobicity of ptfe is crucial for automatically operating equipment. Let’s talk about it below. Learn about ptfe low-resistance filter membrane.
Air particulate matter (PM) is currently recognized as one of the major air pollutants and has the closest epidemiological connection with various endpoints of population health effects.
A large number of studies have found that exposure to airborne particles can have adverse health effects on the human body.
In recent years, the air purification treatment of PM10 and PM2.5 has achieved preliminary results.
PTFE low-resistance filter membrane has excellent waterproof, moisture permeable, air permeable, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore size of this microporous membrane can be between 0.1-1um, the thickness can be between 10-100um, the porosity can reach 50%-90%, and there are up to hundreds of millions of micropores per square centimeter.
Since the pore size of the microporous membrane is much larger than that of water vapor molecules, and polytetrafluoroethylene (PTFE) is a hydrophobic material, water droplets cannot penetrate the micropores, so it has good moisture permeability, air permeability and waterproofness, and the microporous membrane is resistant to water pressure. Up to 0.1MPa.
Polytetrafluoroethylene (PTFE) also has excellent corrosion resistance, aging resistance and high temperature resistance, and its operating temperature can reach -150℃-250℃.
PTFE film manufacturer specializes in the production of PTFE low-resistance filter membranes. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membranes; the product materials produced They all use imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
