Definitions

  • German patent application 1 95 22 120.6 (state of the art according to ⁇ 3 II PatG) describes an amorphous, transparently colored, UV-stabilized plate made of a thermoplastic that can be crystallized and whose thickness is in the range from 1 to 20 mm.
  • the plate contains at least one UV stabilizer as a light stabilizer and at least one polymer-soluble dye.
  • the plate is characterized by good optical and good mechanical properties
  • the molded PET sheet is taken out of the mold when the degree of crystallization of the molded PET sheet is in the range of 25 to 50%.
  • the PET sheets disclosed in EP-A-0 471 528 have a thickness of 1 to 10 mm. Since the deep-drawn molded body produced from this PET sheet has a high degree of crystallization, there is no possibility of obtaining a transparent object. The molded body is always opaque. In addition, the deep-drawn molded body has poor mechanical properties, in particular poor impact resistance, due to the crystallization.
  • the good optical properties include, for example, high light transmission and a homogeneous appearance.
  • crystallizable polyethylene terephthalate means crystallizable polyethylene terephthalate homopolymers, crystallizable polyethylene terephthalate copolymers, crystallizable polyethylene terephthalate compounds, crystallizable polyethylene terephthalate recyclate and other variations of crystallizable polyethylene terephthalate.
  • the heating or heating of the plate can be carried out with all heating devices known to the person skilled in the art for deep drawing. Hot air ovens or infrared heaters are preferably used for heating the plate.
  • the molded part should be quickly cooled with air or air / spray water.
  • the subsequent demolding preferably takes place only when the molded part has a temperature below 60 ° C.
  • the moldings of the invention have not broken in the measurement of impact strength a n Charpy (measured according to ISO 179/1 D) preferably.
  • the deep-drawn molded body according to the invention has a light transmission, measured according to ASTM D 1003, of more than 80%, preferably more than 84%.
  • the haze of the shaped body measured in accordance with ASTM D 1003, is less than 15%, preferably less than 11%, and the image sharpness of the shaped body, which is also called Clarity, and is determined at an angle of less than 2.5 ° (ASTM D 1003) is preferably above 94% and particularly preferably above 96%.
  • the concentration of the pigment preferably being in the range from 0.5 to 30% by weight, based on the weight of the crystallizable polyethylene terephthalate, the light transmission, measured according to ASTM D 1003, is less than 5%.
  • This size is determined according to ISO 179/1 D.
  • the UV-stabilized plate has the following property profile:
  • the PMMA board has the following property profile:
  • the PET molded body with a crystallization of approx. 35% has the following properties:

Abstract

L'invention concerne un corps moulé amorphe thermoformé d'une épaisseur de 1 à 20 mm, contenant comme principal composant un polytéréphtalate d'éthylène susceptible de se cristalliser, qui se caractérise par de bonnes propriétés mécaniques et optiques. Ce corps moulé peut être au choix transparent, teinté de façon à être transparent ou teinté de façon à être opaque. Dans un mode préféré de réalisation, il est en outre stabilisé aux U.V. L'invention concerne également un procédé de production de ce corps moulé et son utilisation.
