Fabrics Q&A

There are two main methods for preparing U15 high-efficiency filter materials. One is to add the pore-forming agent NaCl to PTFE, then make the PTFE into a film, and then remove the NaCl by heating and washing …

Due to the different characteristics of clean rooms, the selection of high-efficiency filters must first be determined according to the different requirements of the clean room, such as level, sterility, temper…

Air filters are divided into primary-efficiency air filters, medium-efficiency air filters, and high-efficiency air filters according to the filtration level; primary-efficiency air filters are generally used f…

The filter levels are divided into coarse-efficiency filters (G1~G4), medium-efficiency filters (F5~F9), high-efficiency filters (H10~H14), and ultra-high-efficiency filters (U15~U17), for general civilian use …

U15 grade high-efficiency filter material is suitable for various clean rooms from grade 1 to grade 100000. It adopts a special processing technology and is a microporous film made by calendering, extrusion, bi…

PTFE reusable mask filter membrane is mainly due to its use of materials with smaller fiber diameter compared with traditional masks. Generally speaking, the fiber diameter of the ordinary non-woven material us…

Yes, PTFE ultra-wide film is made of polytetrafluoroethylene. It is expanded and stretched to form a microporous film. This film is laminated on various fabrics and substrates using a special process. , can pla…

The pore size of the microporous membrane is relatively uniform, the porosity is high, there is no medium shedding, the texture is thin, the resistance is small, the filtration rate is fast, and the adsorption …

The porosity of ptfe ultra-wide membrane is as high as 80%, the average pore diameter is 0.2μm, and it has dimensional stability, chemical resistance and high and low temperature resistance, making it occupy an…
