Title (EN) ENVIRONMENTALLY DEGRADABLE POLYMERIC BLEND AND PROCESS FOR OBTAINING AN ENVIRONMENTALLY DEGRADABLE POLYMERIC BLEND
(FR) MÉLANGE POLYMÉRIQUE BIODÉGRADABLE ET MÉTHODE DE PRODUCTION D'UN MÉLANGE POLYMÉRIQUE BIODÉGRADABLE
Abstract: front page image
(EN)The present invention refers to an environmentally degradable polymeric blend, comprising biodegradable polymers defined by polyhydroxybutyrate (PHB) or copolymers thereof and Polycaprolactone (PCL) and, optionally, at least one additive defined by a filler, nucleant, thermal stabilizer, processing aid, with the purpose of preparing an environmentally degradable polymeric blend. According to the production process described herein, the blend resulting from the mixture of the biodegradable polymers, PHB and PCL, and at least one additive, can be utilized in the manufacture of injected food packages, injected packages for cosmetics, tubes, technical pieces and several injected products.
(FR)La présente invention concerne un mélange polymérique biodégradable qui comprend des polymères biodégradables constitués de polyhydroxybutyrate (PHB) ou des copolymères de ce dernier et de polycaprolactone (PCL) et, éventuellement, d'au moins un additif constitué d'une charge, d'un nucléant, d'un stabilisant thermique, d'un additif de traitement, servant à produire un mélange polymérique biodégradable. Selon la méthode de production de l'invention, le produit résultant du mélange des polymères biodégradables, du PHB et du PCL, et du ou des additifs peut être utilisé pour la fabrication d'emballages de produits alimentaires moulés par injection, d'emballages moulés par injection pour produits cosmétiques, tubes, pièces techniques et divers autres produits.
