When carrying out purification engineering construction in a clean room, a lot of equipment is needed, and the core of these equipment is almost always made of polytetrafluoroethylene film.
The reason is that the polytetrafluoroethylene film has a fibrillar microporous structure, the porosity can reach more than 85%, there are 1.4 billion micropores per square centimeter, and the pore diameter ranges from 0.02um to 1.5um, which can capture Most dust particles prevent dust from entering the membrane through the surface of the membrane.
The filtration accuracy of the membranes produced by polytetrafluoroethylene film manufacturers can reach U15 level (99.9995%) or even U17 level (99.999995%), which can fully meet the purification requirements of high-precision electronic product processing workshops such as semiconductors and chips. .
