Product Description
◆ Name: Polyvinylidene fluoride microporous membrane
◆ Grade: Industrial/Food/Pharmaceutical Grade.
◆ Performance:
1.Naturally hydrophobic, or changed to hydrophilic.
PVDF microfiltration membrane rolls include hydrophilic and hydrophobic types, Hydrophilic polyvinylidene fluoride (PVDF) membranes have very low protein adsorption compared to other membranes such as nylon, NC, and PTFE membranes, as well as higher water flow rates and Broad chemical compatibility, Therefore PVDF membranes are often used for sterile filtration of culture media and other protein solutions.
2.The hydrophobic PVDF membrane adopts the production process after the actual verification. It has super hydrophobic properties and can be used for solvent filtration, air and gas filtration, and sample preparation in HPLC and GC. It has excellent heat resistance and oxidation resistance. Has a very wide range of applications.
◆ Type: Flat Sheet (Roll)
◆ Application: Filtration of Liquids & Gases.
◆ Aperture: conventional 0.05/0.1/0.22/0.45/1.0/3.0/5.0/10um, can be customized.
