Filtration Without Compromise.
The membrane industry has been settling. We're not.
Solvents. Strong acids. Oxidants. Aggressive cleaning cycles. The conditions that swell, degrade, and destroy conventional membranes are the conditions Nexion's poly(ether-ether-ketone) PEEK platform was built to run in. PEEK is one of the most chemically inert engineering polymers on earth. Nobody had made it into a membrane. We did.
It holds where polymers dissolve and ceramics cost too much.
​
We're not here to iterate on what already exists.
We're here to replace it.

Targeted Sectors.
PEEK doesn't care what industry you're in. It just performs where everything else fails.
Nexion's membrane platform is built for any process that demands resistance to organic solvents, acids, bases, aggressive cleaning cycles, high temperatures, pure mechanical punishment, and biological inertness. Whatever your sector, if your current membranes are failing, underperforming, or simply not built for what you're putting them through, we want to hear from you.
Biopharma
Life Sciences
ADCs, peptides, and oligos place demands on membranes that conventional materials weren't designed for. PEEK's chemical resilience, biological inertness, and cleaning durability make it a compelling material for next-generation bioprocessing.
Analytical and laboratory filtration requires materials that are chemically compatible and reliable across a wide range of conditions. PEEK is well suited for demanding life sciences workflows.
Radiopharma
Radionuclide production and purification subject membranes to hot acids, organic solvents, radiolysis, and aggressive decontamination. Conventional polymers degrade; ceramics are impractical at this scale. PEEK's chemical inertness and radiation stability make it a rare fit for one of the harshest duties in pharmaceutical manufacturing.
API & Fine Chemicals
Solvent recovery, catalyst recovery, and clarification in aggressive process streams. Distillation is energy-intensive and thermally damaging; conventional membranes dissolve. PEEK holds where the process chemistry does the damage.
Chemical & Solvent Recovery
Organic solvents, strong acids, strong bases, and elevated temperatures. Polymeric membranes fail; ceramics work but cost too much. PEEK offers ceramic-class chemical resistance in a polymeric format.
Critical Minerals & Hydrometallurgy
Hot acid leachates, solvent-extraction streams, and acid recovery in refining and battery recycling. Currently served by ceramics or by nothing.
