Hangzhou Tanvi Filtering Equipment Co., Ltd sell "PES PTFE PVDF Nylon Pleated Filter Cartridge"

These absolute-rating pleated filter cartridges combine uniform pore structure and high porosity with polypropylene support layers, assembled by hot-melt welding rather than adhesive so no bonding medium can shed into the process. The design delivers high flow and long service life, making it widely used for sterilizing filtration of aqueous solutions.
