In recent years, as people’s requirements for product quality continue to increase, Teflon H13 high-efficiency filter paper has also been widely used in clean rooms. The function of a clean room is to control the cleanliness, humidity and other indicators of the air that the products produced in it come into contact with to meet standards, so that products can be produced in an environmental space with good conditions and high stability.
High efficiency/ultra high efficiency filter is the “heart” to ensure the cleanliness of the clean room. With the continuous advancement of technology, the structure of high-efficiency filters has undergone a structural transformation from filters with partitions to filters without partitions. With the change in structure, it has also brought about a substantial improvement in efficiency. Currently, semiconductor clean filters The high-grade ultra-high-efficiency filter can reach the filtration efficiency of U17 (99.999995%@0.1～0.2μm). In addition to changes in structural form, the core filter materials of high-efficiency/ultra-high-efficiency filters are also constantly innovating. Very fine glass fiber filter paper is a traditional high-efficiency/ultra-high-efficiency filter material. It has the advantages of wide efficiency range, high dust holding capacity, long service life, and good flame retardancy. But it also has the disadvantages of high resistance, high brittleness, intolerance to moisture, high outgassing, and inability to degrade. The birth of PTFE filter material has largely made up for the shortcomings of glass fiber filter material. It has many advantages such as low resistance, good toughness, and low outgassing.
CurrentlyTeflon H13 high-efficiency filter paper is the core filter material of high-efficiency filters in clean rooms. Teflon H13 high-efficiency filter paper has excellent breathability, corrosion resistance, aging resistance, 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%, there are up to hundreds of millions of micropores per square centimeter, and the filtration grade can reach H13-U16. It can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C. Interested parties are welcome to enter the store for consultation.
