Patent

CA 2332980

The present invention relates to shape-formed, three dimensional, moisture vapour permeable, liquid impermeable articles comprising moisture vapour permeable, liquid impermeable structures comprising a thermoplastic composition. The thermoplastic compositions comprise preferred thermoplastic polymers and suitable hydrophilic plasticisers that also enhance the moisture vapour permeability of structures, e.g. films or layers, made from the thermoplastic compositions. The shape-formed three dimensional articles of the present invention can find a variety of applications wherein moisture vapour permeability combined with liquid imperviousness are desirable.

L'invention concerne des articles façonnés tridimensionnels, perméables à la vapeur d'eau, imperméables aux liquides comprenant des structures perméables à la vapeur d'eau, imperméables aux liquides contenant une composition thermoplastique. Ces compositions thermoplastiques contiennent des polymères thermoplastiques préférés et des plastifiants hydrophiles appropriés qui augmentent également la perméabilité à la vapeur d'eau de ces structures, par exemple, des feuils ou des couches constitués par ces compositions thermoplastiques. Ces articles peuvent être mis en application dans une variété de domaines nécessitant une perméabilité à la vapeur d'eau combinée à une imperméabilité aux liquides.
