Reticulated Polyurethane Foam For Medical Devices

Mon, 07/07/2008 - 5:03am

LISTED UNDER:



Polyurethane foam is suited for a variety of medical/healthcare products and applications for filtering, absorbing, wiping, and padding. Foam consists of a thin membrane of polyurethane encapsulating a network of open cells. The reticulation process subjects the foam to heat and pressure to remove the membrane, producing an open-pore reticulated foam with a skeletal structure. The different polymer types available (polyester and polyether) combined with a range of pore sizes within each type, provide controlled permeability, design flexibility, and a pleasing aesthetic appearance. The foam can also be produced with various densities to affect its structural and mechanical properties.
