  • Patent number: 11981110
    Abstract: The present disclosure relates to a multilayer film may include a fluoropolymer based layer that may include a fluoropolymer based material, and an adhesive layer in contact with the fluoropolymer based layer. The adhesive layer may include a first ultra-violet (UV) absorber component. The multilayer film may have a lower ultra-violet light transmission (L-UVLT) of not greater than 1.0%, where the L-UVLT of the multilayer film is defined as the percent transmission between 200 nm and 360 nm. The multilayer film may further have a high ultra-violet light transmission (H-UVLT) of not greater than 5.0%, where the H-UVLT of the multilayer film is defined as the percent transmission between 360 nm and 380 nm. The multilayer film may include a visual light transmission (VLT) of at least about 50.0%, where the VLT of the multilayer film is defined as the percent transmission between 400 nm and 1100 nm.

  • Publication number: 20230192923
    Abstract: The present disclosure relates to a multilayer laminate structure may include a glass substrate having a thickness of not greater than about 300 microns, a fluoropolymer based layer, and an adhesive layer in contact with the fluoropolymer based layer and between the glass substrate and the fluoropolymer based layer. The adhesive layer comprises an adhesive component and a first adhesive layer ultraviolet (UV) absorber component. The multilayer laminate structure may have a lower ultraviolet light transmission (L-UVLT) of not greater than 1.0%, a high ultraviolet light transmission (H-UVLT) of not greater than 5.0%, and a visual light transmission (VLT) of at least about 50.0%.

  • Publication number: 20120282437
    Abstract: A textured film is provided. The textured film includes a first layer forming an outer surface and including a fluoropolymer. A second layer includes an encapsulant layer. The first layer and the second layer are mechanically textured to provide a plurality of surface features on the outer surface and extend into the second layer. The film can be applied as a textured film overlying an active component of a photovoltaic device.

  • Publication number: 20120201865
    Abstract: A hot-melt extruded composition is disclosed that includes about 20-80% wt. of a plant-derived phenolic material; about 20-85% wt. of one or more edible or bioerodible excipients; about 0-40% wt. of a surface active material; about 0-40% wt. of an oral absorption enhancer; and about 0-10% wt. of one or more pharmaceutical or food grade additives. The composition has been hot-melt extruded at a temperature substantially below the melting point of the plant-derived phenolic material to produce a hot-melt extruded composition wherein substantial degradation of the plant-derived phenolic material has not occurred.
