Title
(EN) BIODEGRADABLE DRAIN BOARD
(FR) PANNEAU DE DRAINAGE BIODÉGRADABLE
Abstract
(EN) The invention provides for a core of a drain board manufactured from a composition comprising a. a polyester comprising one or more hydroxycarboxylic acids as monomers, b. a copolyester comprising at least one diol component and at least one diacid component, c. an inorganic filler, wherein the composition comprises at least 5 wt.% of the inorganic filler, based on the total weight of the composition. The invention also provides for a process for manufacturing the core of the drains board and a biodegradable drain board.
(FR) L'invention concerne un noyau d'un panneau de drainage fabriqué à partir d'une composition composée : (a) d'un polyester comprenant un ou plusieurs acides hydroxycarboxyliques en tant que monomères ; (b) d'un copolyester comprenant au moins un composant diol et au moins un composant diacide ; (c) d'une charge inorganique. La composition comprend au moins 5 % en poids de la charge inorganique, sur la base du poids total de la composition. L'invention concerne également un procédé de fabrication du noyau du panneau de drainage et un panneau de drain biodégradable.
