PTFE black film made by biaxial stretching method. The surface of the membrane can reach more than one billion micropores per square centimeter. The diameter of each micropore (0.1μm-0.5μm) is hundreds of times…

Stretching ratio and stretching temperature have obvious effects on the tensile strength and elongation at break of ptfe biaxially stretched film. Compared with unstretched polytetrafluoroethylene tape, the str…

Air filtration mainly uses H14 grade high-efficiency filter material. This medium will absorb solid impurity particles floating in the air, thereby filtering impurity particles, oil mist and dust in the air to …

With the development of society and the increase of population, air pollution is increasing. In addition to the pollution caused by daily life, part of it is caused by industrial production and machine producti…

Ordinary filter materials include traditional needle punched felt, woven filter materials, etc. The working principle is the so-called “depth filtration” technology, that is, through the collection …

The H14 grade high-efficiency filter material can exert its superior characteristics regardless of the lifetime dust cleaning mechanism. It is a filter material designed to fully exert its high-efficiency filtr…

The H13 high-efficiency filter material is a microporous membrane made of dispersed polytetrafluoroethylene resin and various substrates. The main feature of this filter material is surface filtration, which ca…

The H13 grade high-efficiency filter material has a smooth surface and is resistant to chemicals. It is laminated to the surface of ordinary filter materials and functions as a disposable dust layer, trapping a…

Clean room FFU filter membranes are generally required to have large voids, low filtration resistance, large throughput, and strong dirt holding capacity, which can improve filtration efficiency, extend service…
