Flat Sheet and Capillary Filtration Membranes

3M produces a broad range of microporous flat sheet and capillary membranes for use in various industries.

Our capillary and flat sheet hydrophobic and hydrophilic membranes are made from a variety of materials, such as polyethersulfone and polypropylene, to meet highly diversified market requirements. 3M supplies these membranes to filtration module manufacturers or cartridge producers to incorporate into their final products.

Polyethersulfone (PES) Membrane Technology Platform

Our production technology and controls allow us to fabricate self-supporting PES membranes. By casting an asymmetrical pore structure using the SIPS process, 3M produces a reliable portfolio of microfiltration membrane products in MicroPES® and DuraPES®.

Polypropylene (PP) Membrane Technology Platform

PP hydrophobic polyolefin membranes are produced using a TIPS pro­cess. As a result of this sophisticated manufacturing procedure, 3M™ Flat Membrane MF-PP Series provide high porosity combined with uniform pore dis­tribution throughout the thickness of the membrane.

3M can also supply flat sheet membranes with customized width which can be slit either from 10’’ or 20’’wide standard rolls. Slitting equipment is operated under controlled area conditions
