There are really too many types of non-woven fabrics on the market now. I believe many people are not sure about the specific materials of non-woven fabrics. Today I will tell you about clean room high-efficiency filtration membranes.
The early 1960s was the initial stage of the development of clean technology in China, roughly ten years later than abroad.
It was a very special and difficult era, with a weak economy and no strong-country diplomacy. Under such difficult conditions, China’s clean technology workers began their own entrepreneurial journey around the needs of precision machinery, aviation instrumentation and electronic industries.
Clean room high-efficiency filtration membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and processed by calendering, extrusion, and biaxial stretching.
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%, and there are up to hundreds of millions of micropores per square centimeter.
The highest precision of the clean room high-efficiency filtration membrane can reach H14 level (99.995%) or above. Since the micropore diameter is tens of thousands of times larger than water molecules and hundreds of times smaller than water droplets, it has excellent moisture permeability, air permeability and waterproof properties. .
It is currently the most widely used microporous organic membrane.
PTFE membrane manufacturer specializes in the production of clean room high-efficiency filtration 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 membrane; 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.
