Title
(EN) METHODS FOR DISPENSING AND FORMING 3A MOLECULAR SIEVE HOT MELT ENTRAINED POLYMERS ONTO SUBSTRATES
(FR) PROCÉDÉS DE DISTRIBUTION ET DE FORMATION DE POLYMÈRES THERMOFUSIBLES ENTRAÎNÉS PAR TAMIS MOLÉCULAIRE 3A SUR DES SUBSTRATS
Abstract
(EN) Disclosed are methods for forming and adhering an entrained polymer structure to a substrate. The methods include providing a substrate configured to receive application of a molten entrained polymer. A 3A molecular sieve entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least a base polymer and 3A molecular sieve. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer.
(FR) L'invention concerne des procédés de formation et de collage d'une structure polymère entraînée sur un substrat. Les procédés consistent à fournir un substrat conçu pour recevoir une application de polymère entraîné fondu. Un polymère entraîné par tamis moléculaire 3A sous forme fondue est appliqué sous une forme prédéfinie, à une surface du substrat, pour former une structure polymère entraînée solidifiée sur le substrat. Le polymère entraîné comprend un matériau monolithique formé d'au moins un polymère de base et d'un tamis moléculaire 3A. La surface du substrat est compatible avec le polymère entraîné fondu de façon à se lier thermiquement à celui-ci. De cette manière, le polymère entraîné se lie au substrat et se solidifie en cas de refroidissement suffisant du polymère entraîné.
