Our PTFE membrane filter cartridges feature a corrosion-resistant PVDF structure. The full-fluoropolymer filter layer is composed of polytetrafluoroethylene (PTFE)/hydrophilic PTFE membrane, while the housing, center rod, and end caps are meticulously crafted from PVDF material. This structure ensures superior resistance to chemical corrosion, enabling the efficient and extended filtration of highly corrosive chemicals like acids, alkalis, and organic solvents.
