Brief of Membrane


PES (polyether sulfone) is high chemical, thermal stabile and has fast-flowing ability, acid and alkali resistant ability ( PH range 1-14), with high mechanical strength.


PVDF(polyvinylidene fluoride) has chemical stability and inertness which is applicable to chemically aggressive organic solvents, strong acids and alkali solution and sample preparation of HPLC (high performance liquid chromatography) analysis. It’s hydrophobic to filter off moisture in the air, gases and is laminated on supporting net for its strong strength, operability. Preferably, it’s resistant to a high temperature of 130 degrees.


NYLON(organic nylon 66) is applicable in most organic solvents and aqueous solution, for instance, organic solvents of strong acid, 70% ethanol and methylene chloride. It has good strength, chemical stability and high temperature resistant ability.
