Abstract
Procédé de production d'une mousse thermoplastique comprenant les étapes suivantes: a) fusion d'un polymère thermoplastique pour obtenir un polymère en fusion; b) introduction d'un agent de soufflage à base de dioxyde de carbone dans le polymère en fusion; c) adjonction à ce polymère en fusion d'un ou plusieurs additifs choisis dans le groupe constitué par: 1) le polysiloxane, et 2) une huile minérale; et d) extrusion et moussage du polymère en fusion, de l'agent de soufflage et d'un ou plusieurs additifs pour obtenir thermoplastique. La mousse thermoplastique ainsi obtenue peut être mise en forme pour constituer divers articles en mousse, comme des plateaux de conditionnement. La qualité des mousses réalisées à l'aide d'un agent de soufflage contenant du dioxyde de carbone et, en particulier, contenant 100 % de dioxyde de carbone, s'est révélée considérablement améliorée avec l'adjonction d'un ou plusieurs des additifs précités, c'est-à-dire le polysiloxane, une huile minérale et, éventuellement, une polyoléfine au polymère en fusion au cours de l'extrusion et du moussage. Les mousses présentent beaucoup moins de ruptures de cellules, de fissurations et d'ondulations superficielles que les mousses comparables réalisées avec un agent de gonflage au dioxyde de carbone mais sans l'un des additifs visés par la présente invention.
