The porosity of ptfe high-efficiency filter paper filter material can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5u…

PTFE composite filter paper is widely used because of its “high uniformity, stable performance and good air permeability”. It also has high filtration efficiency and can meet the filtration efficien…

PTFE composite filter paper is laminated on various fabrics and substrates using a special process and can become a new type of filter material. It has excellent corrosion resistance, aging resistance and high …

The pore size of the ptfe porous membrane is small and the distribution is concentrated, which can better prevent fine dust from entering the filter material, just like a first layer of artificial dust, achievi…

PTFE porous membrane is made of polytetrafluoroethylene (ptfe) material through a special biaxial stretching process. It has excellent high temperature resistance, low temperature resistance, alkali resistance,…

Not only domestic water, but also water needed in various industries can no longer rely solely on nature’s water cycle. Securing water resources has become a global problem. A key technology to solve this…

PTFE microporous membrane is a filtration membrane made of polytetrafluoroethylene as raw material and made by biaxial stretching technology. The main feature of this filter material is surface filtration, whic…

Microfiltration and ultrafiltration membranes prepared by stretching, phase inversion, etc. have pores that penetrate the membrane body, thereby forming a porous membrane. The mechanism of the porous membrane p…

There are three major indicators to measure the properties of porous membranes: porosity, trapped pore size and pore size variance. Porosity refers to the ratio of the sum of the pore areas in the membrane surf…
