Solvent-resistant crosslink-modified polyamide membrane layer prevents swelling and damage induced by organic solvents.
Featuring corrosion resistance, the sanitary mesh can endure long-duration soaking in weak organic solvents.
Solvent-resistant sanitary NF with 34mil wide runner, adapt feed liquid containing low-concentration alcohol & ester organic solvents, membrane layer resist solvent swelling, maintain stable rejection & flux in organic system.
