Abstract

Process for the manufacture of products of stable structure composed of inflatable polystyrene particles, characterized in that the pre-foamed inflatable polyestitol is treated, after pre-foaming, with steam until reaching a bulk passage of 8 to 100 kp/m3, according to such bulk weight, for 3 to 50 minutes with hot air at 50ºC to 100ºC, after which the treatment is continued in the usual way.
