Victrex Membranes Intro

Do you need solvent stable and temperature resistant filtration solutions from Victrex?

Flat sheet PEEK membranes for microfiltration, ultrafiltration, and nano-filtration may meet the increasing requirements of the pharmaceutical, semiconductor, and fine chemical refining industries. PEEK membranes may deliver solvent stable and temperature resistant (up to 220C) performance for micro and ultra-filtration. Nano-filtration solutions may also be possible. Prototype PEEK membranes are currently available in the market, such as 10nm, 100nm, and 200nm cut-offs in 25mm and 47mm cut discs filters.

Please share with us your needs and why current solutions are falling short.

Benefits of VICTREX PAEK-base Membranes*
