  • Publication number: 20060130827
    Abstract: A solar thermal collector comprising multiplicity of chords and webs is disclosed. The first, second and third horizontal chord of the solar thermal collector are connected to one another by webs positioned vertically to said horizontal chords. The first horizontal chord is transparent and the second horizontal chord, which is positioned between the first and third horizontal chords, absorbs thermal radiation and is perforated. The horizontal chords and said webs of the inventive solar thermal collector comprise thermoplastic materials. Producing the solar thermal collector including perforating the second horizontal chord by means of a laser beam is also disclosed.

  • Patent number: 6630216
    Abstract: Described is a molded plastic article which includes a barrier film. The molded plastic article is prepared by a process which involves: (a) providing a barrier film comprising at least one polymeric layer, the barrier film having a first surface and a second surface; (b) placing the barrier film in a mold such that the first surface of the barrier film is in contact with at least a portion of the interior surfaces of the mold; (c) injecting a polymer (e.g., a molten thermoplastic polymer) into the mold, the injected polymer contacting the second surface of the barrier film; and (d) removing the molded plastic article from the mold. Also described are molded articles according to the present invention, which include, for example, plastic containers, plastic fuel tanks, plastic storage units, plastic fascias and plastic motor vehicle interior cladding materials.
