CELGARD® is one of the world’s leading oxygenation membranes with high mechanical stability.

CELGARD capillary membranes are produced by extrusion of Polypropylene. Consecutive anneal and stretch steps create the pores in the capillary wall. This production technology yields a membrane that is mechanically very stable with no compromise in gas exchange performance or plasma breakthrough resistance.


CELGARD capillary membranes are available as six filament spools or as single layer or

double layer cross-wound mats.
