摘要: The present invention is directed toward a polyvinyl acetal sponge with smooth outer low durometer silicone skin having less porosity then the foam center. PVA washed free of formaldehyde, dried and hydrated thin coating than 1 mm applied to surface heated at temperature ranging from 100° F. 150° over 8 16 hours cure bonding it increasing tear strength while preserving elasticity. composite wound dressing allows moisture adsorption through into body but presents an precluding growth material.
