Abstract

This invention refers to polyurethan foam materials the pores of which are free from halogenized hydrocarbon, in particular are free from chlor - fluorinecarbon and method for production of these materials which do not contain halogenated hydro¬carbon, in particular foaming agents used without the use of chlorfluorinecarbons. Polyurethane foam mate¬rials pores contain a small amount of volatile foaming agent selected from the group which com¬prises the low density alkane 3 - 6 with carbon atom and the mixure of the low density alkans, with this, said liquid foaming agent has boiling point from -10 to +700° C at the normal pressure. According to this invention, said foaming agent is either thinly distributed in the mixture of alcohol and isocyanate outlet components or said foaming agent is first emulsified in the alcohol outlet component, if there is need in emulsifying agent, and then inocyanate component is added into this emulsion after which the exothermical polymerization reaction of the outlet components is effected. The obtained polyurethan foaming material can be stored during several hours or days.
