Abstract: Backing films for adhesive tapes are presented, as well as adhesive tapes comprising such backing films, which may include tapes used in construction such as seam sealing tapes, roofing tapes, and flashing tapes. The backing film comprises a core layer, a first skin layer, and optionally a second skin layer, where the backing film has a coefficient of thermal expansion of less than 0.500 measured in at least one direction within the plane of the film, and, in some embodiments, a Young's modulus of less than 550 MPa as measured in at least one direction. In some embodiments, the backing film has a coefficient of thermal expansion of not more than 0.510 and a Young's modulus of not more than 540 MPa as measured in any direction within the plane of the film. In some embodiments, the core layer comprises a polyolefin, and skin layers comprise a thermoplastic elastomer.

Abstract: Backing films for adhesive tapes are presented, as well as adhesive tapes comprising such backing films, which may include tapes used in construction such as seam sealing tapes, roofing tapes, and flashing tapes. The backing film comprises a core layer, a first skin layer, and optionally a second skin layer, where the backing film has a coefficient of thermal expansion of less than 90 ppm/° C. measured in at least one direction within the plane of the film, and, in some embodiments, a Young's modulus of less than 550 MPa as measured in at least one direction. In some embodiments, the backing film has a coefficient of thermal expansion of not more than 91.8 ppm/° C. and a Young's modulus of not more than 540 MPa as measured in any direction within the plane of the film. In some embodiments, the core layer comprises a polyolefin, and skin layers comprise a thermoplastic elastomer.

Abstract: A composite film comprises first and second layers. The first layer comprises a first copolymer of monomers comprising tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, wherein the first copolymer contains at least 35 mole percent of vinylidene fluoride monomer units. The second layer is disposed on the first layer, and comprises a second copolymer comprising 50 to 83 weight percent of ethylene monomer units and at least 17 weight percent of alkyl (meth)acrylate monomer units represented by the formula (I) wherein R1 is H or methyl, and each R2 is independently an alkyl group having from 1 to 4 carbon atoms. Methods of making the composite film and articles including it are also disclosed.
