Abstract:
1. An antimicrobial polyurethane foam comprising a reaction product of: a multi-functional isocyanate component; an aqueous polyol component reactive with the multi-functional isocyanate component; an antimicrobial metallic compound; and a complexing agent, wherein the antimicrobial metallic compound and the complexing agent form a complex, wherein the complex is adapted to allow dissipation of the complexing agent such that the antimicrobial metallic compound is present as substantially the only antimicrobial metallic compound in the antimicrobial polyurethane foam, wherein the complexing agent is selected from amine compounds, ammonium-containing compounds and ammonia, further wherein the polyurethane foam comprises a flexible matrix of polyurethane material defining a plurality of open cells, wherein the antimicrobial metallic compound is uniformly distributed throughout the flexible matrix.
