    Abstract: Polymeric ion conductive layers and electrochromic devices utilizing the same are described. The polymeric ion conductive layer may include a polymer having a Shore hardness of greater than 80A, an electrolyte dispersed in the polymer, and a plasticizer dispersed in the polymer. The polymeric ion conducive layer may have no creep at elevated temperatures. The polymeric ion conductive layer may have an ionic conductivity of greater than or equal to about 1E-5 S/cm, a haze of less than 3%, and a light transmission of greater than or equal to about 80%. An electrochromic device may include a first optically transparent layer, a second optically transparent layer, and electrochromic layers including the polymeric ion conductive layer interposed between the first and second optically transparent layers.

    Abstract: Semiconductive tapes for use with electric cables, such as high voltage power cables, and methods for manufacturing such tapes, are provided. A semiconductive tape comprises a first layer comprising a fabric and a second layer in contact with the first layer. The second layer comprises an activated carbon or carbon black. The semiconductive tapes have increased friction while still maintaining sufficient electrical conductivity for use as wrappings for electric power cables, thereby improving the manufacturing process and reducing the overall cost of production.

    Abstract: Compositions, laminates, films and/or composites made from thermoplastic polymers, such as thermoplastic polyurethane (TPU) are described. The films have one or more optical layers made from materials that allow the transmission of visible light and reflect or absorb UV light. An optical film is made from one or more TPU resins including a first UV absorber of the benzotriazole family or the triazin family, a light stabilizer, and a second UV absorber selected from a group consisting of benzotriazoles, benzophenones, triazin or benzylidene malonate. The second UV absorber may be present in a base resin combined with the TPU resin. The optical film is capable of blocking at least 99% of light having a wavelength
