DIW and chemical filtration, separated by duty.
The same membrane label can behave differently in water, acids, bases, solvents, photoresist or slurry. Start with the liquid and process position before comparing construction.
Chemical
Fluoropolymer, polyolefin, nylon and depth-filter routes for wet process, lithography, electronic chemicals and CMP.

Every liquid family has one primary home.
Families that serve both water and chemistry are described once, then cross-linked to prevent duplicate specifications and unclear ownership.
| Product family | Construction route | Primary duties | Supply identity |
|---|---|---|---|
| Pleated water cartridge | PP or hydrophilic PES | DIW, UPW, rinse and compatible dilute aqueous duties | Quotation-confirmed |
| Water-ready compact filter | HDPE, nylon, PTFE or other confirmed media | Developer, DIW, solvent and tool POU positions | Zhongfu options Sourced options |
| All-fluoropolymer chemical cartridge | PTFE membrane with PFA structure | Electronic chemicals, CDS, wet etch and cleaning | Zhongfu engineered |
| Semi-fluoropolymer chemical cartridge | PTFE membrane with PP or HDPE structure | Compatible electronic chemical and CDS duties | Zhongfu engineered |
| Photochemical cartridge and POU | HDPE, UPE, nylon, PTFE or PES by route | Photoresist, developer, solvents and selected DIW positions | Zhongfu options Sourced options |
| CMP and slurry filter | Hydrophilic nylon, graded PP or integrated PP | Selected ceria, silica or alumina slurry screening | Zhongfu nylon Other routes sourced |
| Capsule and laboratory filter | Multiple media and low-hold-up formats | Pilot, analytical, small-batch and development work | Quotation-confirmed |
| Liquid filter housing | PP, PFA or stainless steel | Water or chemical service after material and seal review | Quotation-confirmed |
No third-party brand, model, certification or performance value is transferred by this classification. Sourced-product manufacturer, country of origin, controlled data and availability are confirmed in the quotation.
Selection logic
Water quality and chemical compatibility are different decisions.
DIW selection prioritises water quality, particle target, cleanliness, flow and pressure loss. Chemical selection adds formulation-specific compatibility, temperature, seals, extractables, adsorption and process interaction.
DIWQuality target, flow, pressure drop, temperature and installation position.
CHEMICALChemistry, concentration, SDS, temperature, materials and validation target.
