UHMW-POF filter membrane

Name: UHMW-POF filter membrane   

Type: Single-layer porous film, unsupported, non-laminated.

Material: 100% UHMW-POF (ultra-high molecular weight polyolefin), fluorine-free, homogeneous.

Temperature Resistance: Melting point 135°C, recommended long-term operating temperature <60°C.

Chemical Compatibility: Resistant to common chemicals and polar solvents.

Weldability: Suitable for adhesive bonding, hot melt lamination, and ultrasonic welding.

Working way: The pores of the membrane will screen the medium by pore size. The medium with large particle size will be retained on the membrane surface, and the smaller medium will pass through with the liquid and remain in the liquid.

Models and Basic Data:

* PMI pore size analysis: pore size range, average pore size, porosity.

* Pore size retention efficiency: Standard particle count.

* Molecular weight cutoff efficiency: Bovine serum albumin, PEG.

* Surface properties: Contact angle measurement.

Standard Size: (Roll)

Width: 254-1000mm （customizable）

Length: 100m (min)
