Title
(EN) THE USE OF MICROWAVE ENERGY TO SELECTIVELY HEAT THERMOPLASTIC POLYMER SYSTEMS
(FR) EMPLOI DE L'ÉNERGIE MICRO-ONDE DANS LE CHAUFFAGE SÉLECTIF DE SYSTÈMES POLYMÈRES THERMOPLASTIQUES
Abstract
(EN)
A method for processing a thermoplastic material that comprises a microwave-sensitive polymeric region, wherein the method includes exposing the microwave-sensitive polymeric region to microwaves; wherein the exposing results in an increase in the temperature of the polymeric region; and processing the thermoplastic material is disclosed.
(FR)
La présente invention porte sur une méthode de transformation d'un matériau thermoplastique qui comprend une région polymère sensible aux micro-ondes, ladite méthode incluant l'exposition de la région polymère sensible aux micro-ondes à un rayonnement micro-onde; ladite exposition résultant en une augmentation de la température de la région polymère; et la transformation du matériau thermoplastique.
