The composite film may further have a VLT of at least about 93.0% and a haze value of not greater than about 3%.

Disclosed is a heat insulator comprising a substrate comprising of a bulk of silica-based inorganic fiber containing a hydroxyl group; a metallic or ceramic infrared mediator held on at least a part of one surface of the substrate; and a silica cured product holding the infrared mediator on/in the substrate. As the infrared mediator, a metal foil or a ceramic particle may be used. This heat insulator exhibits excellent heat insulating performance in a high temperature range of 600° C. or more, and can be molded into a three-dimensional shape which can be directly mounted to a structure.

A display device includes a panel, a backlight, and an adhesive tape. The backlight is placed under the panel. The adhesive tape has a light blocking property and is bonded to an end face of the panel and the backlight.

Described herein are UV reflective particles, and methods of forming UV reflective particles, comprising extruding a film having a plurality of alternating layers of polycarbonate (PC) and poly(methyl methacrylate) (PMMA), wherein each layer is less than 150 nm thick, and grinding the film into particles having a median particle size less than 200 microns.

The invention relates to a dark thermoplastic polymer composition, which when formed into a film has an ultra-low heat buildup, is visibly opaque, and has a high NIR transmission. The dye system involves two or more IR transparent dyes that combine to produce a color having an L value of less than 40, preferably less than 30, and a heat buildup of less than 50° F., preferably less than 45° F. In one embodiment, the composition is jet black. The composition may be a free-standing film, or a capstock used over a substrate, preferably a white substrate.
