Polypropylene Hollow Fiber Membrane

Hollow Fiber Polypropylene Membrane is produced in house by heat and streatch method from clean food grade PP.

Such membrane is hydrophobic, standard table contact angles apply.

P60

Clean food grade homo-polypropylene, naturally hydrophobic.
Pore size below 0.1 µm
OD/ID is 310/240 µm
No-skin, homogenous wall structure.

Suitable for:
degassing, contactor applications (liquid/liquid and liquid/gas), Membrane Distillation, filtration

P80

Clean food grade homo-polypropylene, naturally hydrophobic.
Pore size below 0.1 µm
OD/ID is 530/440 µm
Inside/out with particles in lumen
No-skin, homogenous wall structure.

Suitable for:
degassing, contactor applications (liquid/liquid and liquid/gas), Membrane Distillation, filtration

Custom

To a small extent we can modify the membrane parameters.

Membrane Outer Diamater can be from 200 to 800micro

Volumetric porosity around 45%

We can not permanently coat the membrane.

Also we can not modify physics, increasing porosity will decrease mechanical strength, increasing OD without increasing wall thickness will cerate mechanical problems, larger wall size will increase trans membrane pressure drop. All these parameters are linked, usually in unwanted way.

There is a MOQ on this product, it takes long time to fine tune the production.

Capillaries

Clean food grade homo-polypropylene or PE.

Not membrane, just polymer capillaries with specific ID/OD, down to 25/360 micro

Suitable for: medical and chemical industries.

There is a MOQ on this product, it takes long time to fine tune the production.

Hollow Fiber Membrane Modules

P60, P80 and custom membrane can be used in all our modules.

Some combinations of membrane type and module type we keep in stock, rest has to produced to order.

Smaller OD of the membrane means larger active membrane surface. For example Module D50 PC P60 has active membrane surface 5m² while Module D50 PC P80 only 1.5m², but has larger lumen flow and pressure drop along the fibers.
