Abstract

Thermoplastic synthetic resin foam articles are described which, in accordance with machine production, are elongated principally in the longitudinal direction and have a cross sectional dimension of at least 6.35 mm and a cross sectional area of at least 51.6 cm<2>, where the cells have a mean cell size in the range from 0.1 to 1.2 mm. These cells contain at least one low-permeability halogenated blowing agent. The blowing agent remains in the cells during use of the foam articles, for example for insulation purposes, and there is no significant release thereof into the atmosphere. On the one hand, this prevents readily volatile halogenated blowing agents entering the ozone layer around the earth, where they can have a damaging effect, and on the other hand very low thermal conductivity of the foam articles is achieved, significantly lower than that of the corresponding foam articles containing air instead of the low-permeability blowing agents.
