Title (EN) BIODEGRADABLE FOAM MOULDINGS OF THERMOPLASTIC STARCH
(FR) MOULAGES DE MOUSSE A PARTIR D'UN AMIDON THERMOPLASTIQUE BIODEGRADABLE
Abstract:
(EN) A method is described for producing foam mouldings of a biodegradable thermoplastic polymer, in particular starch, which involves the polymer being fused at elevated temperature in the presence of water and being made into thermoplastic granules/pellets, the granules/pellets being introduced into a mould and being foamed by electromagnetic radiant energy being supplied.
(FR) On décrit un procédé de production de moulages de mousse à partir d'un polymère thermoplastique biodégradable, en particulier l'amidon. Le procédé consiste à fondre le polymère à une température élevée en présence d'eau, en vue d'obtenir des granules ou pastilles thermoplastiques. Lesdites granules ou pastilles thermoplastiques sont ensuite placées dans un moule pour y être transformées en mousse par application d'une énergie électromagnétique rayonnante.
