Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

A decorative asphaltic membrane that comprises a lower non-stick layer; an intermediate layer composed of a support between two layers of plastic and oxidized modified bitumen wherein the support is a polyethilene; an upper layer composed of three sheets: a lower metallic sheet, preferably aluminium, an intermediate polyester sheet and an upper polyethilene sheet wherein the polyester sheet provides a superficial printing with different chromatic patterns on its lower face. The printing imitates, not exclusively, bricks, tiles, lawn, wood, stone, texts, sports logotypes or those belonging to institutions and/or enterprises. The manufacturing process of the asphaltic membrane comprises the steps of: a. printing the lower face of the polyester sheet with a flexographic process or a hollow engraving process; b. drying the printing; c. laminating said printed polyester sheet between a polyethilene sheet and a support sheet forming the upper layer; and d. laminating said upper layer with an intermediate layer and a lower non-stick layer, wherein the intermediate layer is, in turn, a lamination of a polyethilene sheet between two layers of plastic or oxidized modified bitumen.

The present invention relates to a multilayer film comprising a layer (a) and a layer (c), in each case based on at least one propylene copolymer in an amount of at least 15% by weight, at least one propylene polymer in an amount of at least 40% by weight, in each case based on the total weight of the layer (a)/(c), at least one multi-ply inner layer (b) based on at least one homo- and/or copolyamide comprising isophoronediamine units as a polyamide component, adhesion promoter layers (d) and (e), wherein the thickness of the multi-ply layer (b) is at least 40% of the total thickness of the multilayer film, preferably at least 45% or at least 50%.
