SFP/SFD2660 UF Membrane for Electronic Grade Ultrapure Water DupPont DOW Equivalent

Precision Filtration for Ultrapure Applications

The SFP/SFD2660 ultrafiltration membrane equivalent has been engineered specifically for applications requiring electronic grade ultrapure water, where particle removal down to sub-0.03 micron level is critical. With a robust hollow fiber structure and superior material composition, this membrane effectively removes colloids, bacteria, and ultra-fine particulates that other filtration stages may miss. It is ideally suited for integration in the final treatment stage of UPW production, where maintaining 18.2 MΩ·cm resistivity and TOC levels below 5 ppb is essential.

Dupont DOW Equivalent Performance

✅Filtration efficiency (≥ 99.999% for particles above 0.03 µm)

✅High permeability for stable flux under low transmembrane pressure

✅Chemical resistance to commonly used sanitization agents like hydrogen peroxide and sodium hypochlorite

✅Thermal resistance for hot water sanitization cycles

These features make the Ultrafiltration Membrane for Electronic Grade Ultrapure Water not only an operational match but also a performance upgrade for many legacy systems.
