Particle containing foam structure |
摘要 |
<p>The present invention relates to a method of producing a hydrophilic polyurethane foam structure containing inert particles, such as activated carbon particles. The method comprises the steps of:
a) providing a water phase containing a surfactant and dispersed inert particles;
b) providing a isocyanate-terminated polyether having functionality of more than 2;
c) mixing said water phase and said isocyanate-terminated polyether, immediately transferring the resulting mixture to a mould or a continuous web, whereby a foam structure is obtained; and
d) drying said foam structure until it has a moisture content of at most 10 % (wt). The invention also relates to a foam structure produced by the method and a wound dressing containing the foam structure.</p> |
