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.
