Definitions

  • a method of foaming plastic materials and a blowing agent for use therewith is provided.
  • the present invention relates to a method of foam ⁇ ing plastic, preferably polyurethane, for producing a plastic foam, whereby a liquid plastic substance is brought to expand into foam by admixing and boiling of a blowing agent.
  • foam ⁇ ing plastic preferably polyurethane
  • polyurethane foam it has been traditional to use the blowing agent -ll, but as well known this substance has come under well-founded suspicion of being ozone decomposing, such that for safeguarding the ozone layer of the earth this substance should not be used any longer.
  • FC-134A The boiling point of FC-134A is -26.5°C, and it has been found that this substance is usable not only to ⁇ gether with the said other substance, but even as a substitute for the R-22 in the mixture according to O89/00594, that is where the substance is effective in admixture with 1.1.1. trichloroethane having the boiling point of 75-76°C.
  • the other of the said two substances has a boiling point of 87°C, and the substance is usable with very good results in admixture with FC-134A, but also in admixture with R-22, i.e. as a substitute for 1.1.1. trichloroethane.
  • FC-134A a boiling point of 87°C
  • R-22 i.e. as a substitute for 1.1.1. trichloroethane.
  • the more attractive mixture will be the one with FC-134A, because of its extremely low ozone decomposing effect.
  • blowing agent mixtures consisting of components of mutually different boiling points, but it is an impor ⁇ tant characteristic for the present invention as well as for the invention according to W089/00594 that the mix ⁇ tures here concerned are effective and are handable and operative by atmospheric pressure and ambient working temperature.

Abstract

Les efforts intensifs de recherche de produits de substitution sans danger du fréon utilisé comme agent gonflant dans la production de matières transformées en mousse, n'ont permis jusqu'à maintenant, d'obtenir que très peu de substances utilisables dans des conditions de pression et de température ambiantes. Le mélange de trichloroéthane et de R-22, bien qu'il ait un intêret particulier, présente un certain effet de décomposition de l'ozone. Toutefois, selon l'invention, il est possible de remplacer ces deux substances entièrement ou partiellement par du trichloroéthylène et de tétrafluoroéthane, respectivement, ces substances présentant à la fois une utilisation idoine et une décomposition négligeable de l'ozone.
