    Abstract: An open-celled polyurethane foam formed from a composition comprising an active hydrogen-containing component, an organic polyisocyanate component having an average isocyanate functionality of 2.00 to 2.25, a surfactant component, and a catalyst. The foam has a thickness of about 6 to about 20 mils; a density of about 10 to about 50 pcf; an average cell diameter of about 25 to about 80 microns; and cell openings having an average diameter of about 1 to about 25 microns, wherein the ratio of average cell diameter to average cell opening diameter is about 3 to about 10; a water vapor transmission rate of greater than about 1000 grams per square meter per day, and which do not leak water or similar fluids. Such foams find particular utility as backings for bandages.

    Abstract: A foamed polymeric composition contains polypropylene and polyethylene components. The composition may have a gel content of about 10 to about 95 wt.%, per ASTM D 2765-01, method A, a density of about 16 kg/m 3 to about 640 kg/m 3 and a tensile elongation of at least about 200% at 150 °C per ASTM-1708-02a, speed D. Such a composition can be produced by adding an activatable foaming agent to a base resin that contains polypropylene and polyethylene components and silane functional groups, reacting the functional groups to cause cross-linking to a gel content of about 10% to about 95%, and foaming the cross-linked base resin. Alternatively, a composition may be made by adding an activatable foaming agent to the base resin, irradiating the base resin to cross-link to the stated gel content, and foaming the cross-linked base resin. Articles may be made by molding, shaping or forming such compositions.
