MFFK microfiltration fluoroplastic composite membrane is a porous film on the basis of fluoroplast F42L (copolymer of terephthalate and vinylidene fluoride) supported by various non-woven materials (polypropylene, lavsan) with the pore sizes 0,15; 0,25; 0,45; 0,65; 0,8 microns and total porosity 80-85%.
Application
- Prefiltration and sterilizing filtration of air and gases.
- Microfiltration of aggressive chemicals.
- Microfiltration of alcohols, hydrocarbons, oils, acids, alkalis, organic solvents (except ketones, esters, amide solvents).
Features and advantages
- Resistant to most strong and weak acids.
- Biologically inert.
- High mechanical strength and thermal stability.
- Withstand sterilization by autoclaving and γ-radiation.
