Flexible cellular polyurethane foam products are described. The foams are primarily comprised of: (a) a polyisocyanate component selected from the group consisting of toluenen diisocyanate (TDI), methylene diisocyanate (MDI), monomeric methylene diisocyanate (MDI), polymeric methylene diisocyanate (MDI), toluene diisocyanate (TDI) prepolymer, methylene diisocyanate (MDI) prepolymer, and combinations thereof; (b) an aqueous component including a polyol or polyol blend, or alternatively, a polyol or polyol blend component; and (c) a controlled release antimicrobial component. The resulting flexible cellular polyurethane foam products, containing the antimicrobial component, are suitable for use as wound dressings, or other skin contact (e.g., medical and/or cosmetic) applications. |
