Title (EN) HEAT RESISTANT LIQUID CRYSTALLINE POLYMER PARTS
(FR) PIECES A BASE DE POLYMERES CRISTALLINS LIQUIDES RESISTANTES A LA CHALEUR
Abstract:
(EN) Parts, especially ovenware parts, made from certain liquid crystalline polymers and optionally fillers, reinforcing agents and/or pigments, which have low blistering and/or warpage may be made by addition of small amounts of alkali metal ion to the liquid crystalline polymer and/or certain melt mixing conditions when preparing the composition.
(FR) L'invention se rapporte à des pièces, et notamment à des ustensiles pour la cuisson au four, qui sont fabriquées à partir de certains polymères cristallins liquides et éventuellement de charges, de pigments et/ou d'agents de renforcement, et qui se caractérisent par une faible tendance au cloquage et au gauchissement. Ces pièces peuvent être fabriquées par addition de petites quantités d'ions de métaux alcalins au polymère cristallin liquide et/ou dans certaines conditions de mélange de produits à l'état fondu lors de la préparation de la composition.
