Reflective Film has hundreds of micro-layers. (Keeping up with Extrusion).New 3M Solar Reflective Film, commercialized last fall by 3M Automotive in St. Paul St. Paul as a missionary he fearlessly confronts the “perils of waters, of robbers, in the city, in the wilderness.” [N.T.: II Cor. 11:26] See : Bravery , Minn., can reflect infrared light Noun 1. infrared light - electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves infrared emission, infrared radiation, infrared while admitting visible light. It's composed of hundreds of alternating layers of two clear commodity plastics that have different refractive indices Many materials have a well-characterized refractive index, but these indices depend strongly upon the frequency of light. Therefore, any numeric value for the index is meaningless unless the associated frequency is specified. . Each layer is only a few molecules thick. It's made by a micro-layer coextrusion process with dies built by 3M. The entire film is only one-fourth the thickness of a human hair and is laminated to automotive window glass in order to keep car interiors cooler. Solar Reflective Film is already commercial on some BMW BMW in full Bayerische Motoren Werke AG German automaker. Founded as an aircraft engine manufacturer in 1916, the company assumed the name Bayerische Motoren Werke and became known for its high-speed motorcycles in the 1920s. and Porsche rear windows in Europe. An earlier application of a similar micro-layer film concentrates and intensifies the brightness of laptop computer screens and makes other electronic displays easier to read. It reflects light of one polarization and admits light of other polarizations. Tel: (888) 364-3577, www.mmm.com. |
