Wound dressing comprising polyurethane foam |
摘要 |
A wound dressing has a wound-contact layer formed from a polyurethane foam. The foam comprises one part by weight of the reaction product of an isocyanate-capped prepolymer with water (and optionally other hydroxy-functional compounds), and from 0.03 to 0.3 parts by weight of a natural or synthetic rubber. The isocyanate-capped prepolymer is preferably an isocyanate-capped ethyleneoxy/propyleneoxy copolymer, and the rubber is preferably an acrylic rubber.
