| description | A heat-shrinkable shape memory product is produced by injection moulding a melt-mixed crosslinkable polymer composition, preferably comprising polyethylene and ethylene-vinyl acetate (EVA) copolymer. The composition also contains a micro encapsulated foaming agent and acrosslinking agent, and the temperature and pressure conditions are setlected so that foaming and expansion of the composition takes place not in the injection moulding machine but in the mould itself.
La présente invention concerne un produit à mémoire de forme thermorétractable fabriqué par moulage par injection d'une composition de polymère pouvant être réticulée, mélangée à l'état fondu, comprenant de préférence du polyéthylène et un copolymère éthylène-acétate de vinyle (EVA). La composition contient également un agent moussant micro encapsulé et un agent de réticulation, et les conditions de température et de pression sont sélectionnées de sorte que le moussage et l'expansion de la composition n'ont pas lieu dans la machine de moulage par injection mais dans le moule lui-même. |
