Abstract
High barrier multilayer films are disclosed that incorporate a selectively permeable outer layer and a moisture barrier nanocomposite membrane. More particularly, insulation facing materials and insulation articles can incorporate an insulation facing material having a variable vapor barrier. The facing materials can include a moisture barrier membrane that incorporates a nanoclay.
Claims20
A multilayer film comprising, in order:
- a) a selectively permeable outer layer comprising a polyamide;
- b) optionally an intermediate adhesive primer layer;
- c) a moisture barrier membrane comprising a polyvinylidene chloride nanocomposite, said polyvinylidene chloride nanocomposite comprising an unmodified, non-intercalated, layered nanoclay dispersed in a polyvinylidene chloride polymer;
- d) a first adhesive tie layer;
- and
- e) a fibrous substrate on the first adhesive tie layer.
