Evopor Membrane

Evopor™ membrane is a naturally hydrophilic, supported membrane manufactured to provide uniform wet out and maintain its strength during use in critical filtration applications. Unlike polyethersulfone (PES) and polyvinylidene fluoride (PVDF) membranes, Evopor membranes are comprised of Ethyl Vinyl Alcohol (EVOH) to provide an unparalleled ultra-hydrophilic surface. The support is based on Lydall’s Solupor® membrane and delivers high porosity, superior dimensional strength, higher flux, and ease in handling during cutting, pleating, and sealing in filtration device manufacturing. The membrane is available in roll widths up to 60cm as well as custom cut sheets and disks for the required application.
