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.

2. PVDF+ support, one side coating.(front and back are different)

* PVDF+ UHMW-PO support material,

● High stiffness, long fiber, no risk of shedding.

● Higher temperature and pressure resistance than ordinary support materials,

● The deformation of membrane pores and channel is smaller.

● The membrane can maintain good retention accuracy and correct rate for a long time.


Surface layer: PVDF coating
Support:UHMW material

*PVDF+common support material

● Short fibers, high porosity, honeycomb structure,

● Wedge-shaped asymmetric channel, graded interception and dirt holding.

● Resistance to temperature and pressure is limited by the material.

● Chemical resistance is limited by material.
