Title (EN) BIODEGRADABLE POLYMER FILAMENT
(FR) FILAMENT DE POLYMÈRE BIODÉGRADABLE
Abstract: front page image
(EN)A process for manufacturing a biodegradable polymer filament product, the process comprising: a) isolating polyhydroxyalkanoate from a bacterial culture; b) optionally bleaching the polyhydroxyalkanoate; c) dispersing the polyhydroxyalkanoate in a surfactant solution to form a dispersion; d) drying the dispersion to obtain dried polyhydroxyalkanoate particles; e) mixing the polyhydroxyalkanoate with a plurality of components including a toughening agent, a plasticizer, a nucleating agent, an antioxidant and an adhesive; f) extruding the mixture as a filament; and g) winding the filament onto a spool.
(FR)L'invention concerne un procédé de fabrication d'un produit de filament de polymère biodégradable, le procédé consistant à : a) isoler du polyhydroxyalcanoate à partir d'une culture bactérienne ; b) éventuellement blanchir le polyhydroxyalcanoate ; c) disperser le polyhydroxyalcanoate dans une solution de tensioactif pour former une dispersion ; d) sécher la dispersion afin d'obtenir des particules séchées de polyhydroxyalcanoate ; e) mélanger le polyhydroxyalcanoate avec une pluralité de constituants, comprenant un agent de durcissement, un plastifiant, un agent de nucléation, un antioxydant et un adhésif ; f) extruder le mélange sous forme d'un filament ; et g) enrouler le filament sur une bobine.
