Did you know that the core part of the bag dust removal system (filter bag) is made of corrosion-resistant coated filter material sewn with polytetrafluoroethylene sutures. The main components of the coated filter material include clean room FFU filter membrane. A new type of material.
The final filter of the purification system generally uses a high-efficiency filter or a sub-high-efficiency filter.
According to my country’s standards, the efficiency of high-efficiency filters is divided into four levels: Class A is ≥99.9%, Class B is ≥99.99%, Class C is ≥99.999%, and Class D is (≥0.
1μm particles) ≥99.999% (also known as ultra-high efficiency filter); sub-high efficiency filter (for ≥0.5μm particles) 95~99.9%.
Clean room FFU filter membrane 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%, and there are up to hundreds of millions of micropores per square centimeter.
ptfe film manufacturer specializes in the production of clean room FFU 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 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.
