Poxymem™ Polypropylene Capillary
Cobetter Poxymem PPB-380/280 and PPB-300/200 are porous hydrophobic capillary membranes manufactured by thermally induced phase separation method. The excellent balance of porosity and pore size brings good mechanical strength, large gas transfer and sufficient anti-plasma leakage breaking through ability. It is suitable for applications to substitute lungs in less than 6 hours such as cardiopulmonary bypass surgery and organ perfusion.

Cobetter Poxymem capillary can be delivered in form of mat including single layered mat and double layered cross wounded mat. The mat product is knitted by balanced yarn wrapping force and the capillaries are fixed in certain shapes with little damage to capillaries. This geometry allows great freedom for the following oxygenator device design and massively increases manufacturing efficiency. The cross arrangement of capillaries in double layered cross wounded mat is sufficient to break blood flow boundary layers at capillary surface and thus helps to promote oxygenation performance remarkably.
