MULTILAYER PULTRUDED STRUCTURE HAVING A CHEMICAL RESISTANT AND WEATHERABLE TOP LAYER
20220371313 · 2022-11-24 · ·

The invention relates to a multilayered pultruded structures having a weatherable cap layer over a pultruded substrate. The cap layer provides improved weatherability, chemical resistance and surface quality for pultruded structures. The cap layer is either an acrylic, vinyl or styrenic cap layer covered with a thin layer blend of polyvinylidene fluoride and acrylic polymers, or a cross-linked acrylic outer layer. A useful cap layer would be a UV resistant acrylic cap layer, such as a Solarkote® resins from Arkema, covered by a co-extruded blend of polyvinylidene fluoride, such as Kynar® resins from Arkema, with an acrylic resin, such as Plexiglas® resins from Arkema. The highly weatherable and chemical resistant pultruded structure is especially useful in window and door profiles.

WEDGE-SHAPED MULTI-LAYER INTERLAYER WITH OUTER SKIN LAYERS OF VARYING THICKNESS

Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.

Optical film stack including retardation layer

Optical film stacks are described. More particularly, optical film stacks including a half-wave retardation layer are described. Achromatic half-wave retardation layers, including achromatic half-wave layers formed from a quarter-wave and a three-quarters-wave retardation layer, are described. Film stacks including reflective polarizers tuned to reduce wavelength dispersion of the half-wave retardation layer are also described.
