Characteristics Of Several Commonly Used Membrane Filters

1. Nylon
Features: good temperature resistance, can withstand 121°C saturation steam hot pressure disinfection for 30min, the highest operating temperature of 60°C, good chemical stability, can withstand dilute acid, dilute base, , ester, oil, hydrocarbons, halogenated hydrocarbons, and organic oxides and other organic and inorganic compounds.
USES: electronic, microelectronic, semiconductor industry water filtration, tissue medium filtration. Liquid medicine filtration, beverage filtration high purity chemicals filtration.Filtration of aqueous solution and organic mobile phase.

2. Polyvinylidene fluoride (PVDF) membrane
Features: high mechanical strength, high tensile strength, good heat resistance and chemical stability, low protein adsorption rate; It has strong negative electrostatic property and hydrophobicity. It has two forms: hydrophobic and hydrophilic. However, it could not tolerate c rice, DMSO, THF, DMF, dichloromethane, chloroform, etc.
Purpose: hydrophobic polyvinylidene chloride film is mainly used in gas and steam filtration, high-temperature liquid filtration;
Hydrophilic polyvinylidene chloride (PVDC) membrane is mainly used in tissue medium, additives and other sterilizing filtration solvent and chemical raw material filtration, reagent aseptic treatment, high-temperature liquid filtration.
