The invention relates to a composite for production of an acoustic membrane, wherein the composite comprises an internal carrier layer and at least two adhesive layers on the two surfaces of the carier layer, and wherein the carrier layer is a layer of a polyaryl ether ketone film; and also to a corresponding membrane for acoustic transducers.

A protective film includes an adhesive layer and a base film layer that are stacked. The adhesive layer is configured to adhere to a foldable display. The base film layer includes one or more layers of high-modulus base film and one or more layers of low-modulus base film. An elastic modulus of the high-modulus base film is greater than an elastic modulus of the low-modulus base film. The high-modulus base film and the low-modulus base film are alternately stacked. A surface layer in the base film layer and non-adjacent to the adhesive layer is the high-modulus base film. The protective film is configured to be firmly attached to the foldable display, resists rebounding and warping when the display is bent, and protects the foldable display.

The air and water barrier article includes a polymer-coated inelastic porous layer including a water-vapor permeable polymeric coating disposed on at least one major surface of the inelastic porous layer and an adhesive disposed on a major surface of the polymer-coated inelastic porous layer. The inelastic porous layer can include at least one of surface-modified fibers or natural cellulose fibers. The polymer-coated inelastic porous layer can at least one of a water strike through time of not more than 180 seconds or an absorbance capacity of at least one-half gram per 116 square centimeters. The adhesive may be exposed, in contact with a release surface, or adhered to a surface of a building component. A method of applying the air and water barrier article to a surface of a building component is also disclosed.

The present disclosure provides adhesive mounting articles that can be removed from surfaces without damage by having reduced contribution of a hardgood to the peel force generated by the adhesive article during removal. In some instances, this can be accomplished by a hardgood that is flexible in a peel direction and rigid in a weight hanging direction. Such hardgoods may include a plurality of minimally connected body segments arranged about the transverse axis of the hardgood body.
