Abstract: An all-polymeric cold mirror which reflects visible wavelengths while transmitting a substantial portion of infrared wavelengths is provided. The mirror includes a sufficient number of alternating layers of at least first and second diverse polymeric materials such that at least 50% of peak reflecting visible light of a wavelength of between about 380-680 nm incident on the mirror is reflected and at least 50% of infrared light between about 680-2000 nm is transmitted or absorbed. The mirror may be designed so that it either reflects or absorbs ultraviolet light.

Abstract: A transflection reflector includes a body for simultaneously reflecting and transmitting light rays. The body is formed by a plurality of layers of a polymeric reflective material and has reflected rays at each interface between adjacent ones of the multiple layers. The body is both selectively configured and positioned relative to a light source for a predetermined distribution of reflected and transmitted rays.

Abstract: A multilayered reflective body which is thermoformable and capable of being fabricated into a number of parts while maintaining a uniform reflective appearance is provided. The reflective polymeric body is formed from at least two diverse polymeric materials which differ in refractive index and which are arranged in substantially parallel alternating layers. The polymeric body is reflective in appearance yet is transparent or, colored if a coloring agent is included, upon illumination from a back light source. The polymeric body has application in variety of areas such as in an automobile lighting lens which is reflective and thereby indiscernible yet transmissive upon exposure to a back light source. Additionally, various parts of consumer appliances, for example a refrigerator door, can be formed from the polymeric body.

Abstract: There is an evacuated insulation panel having a corestock of a polymer foam having an open cell content of 70 percent or more. There is a getter material in the interior of the panel to adsorb gases and vapors which may permeate into the panel over an extended period of time.
