(EN) BONDING PROCESS
(FR) PROCÉDÉ DE LIAISON
Abrégé
(EN) The invention relates to a process for bonding a silicone or silicone based material to a polyurethane and use of the bonded silicone-polyurethane in the manufacture of biomaterials, devices, articles or implants, in particular long term implantable medical devices in the fields of cardiology, orthopaedics, plastic surgery and gastroenterology. The process involves the steps of (a) flame treating a surface of the silicone or silicone based material and (b) bonding the polyurethane to the flame treated surface of the silicone or silicone based material.
(FR) L'invention concerne un procédé pour lier un silicone ou une matière à base de silicone à un polyuréthane et une utilisation du silicone-polyuréthane lié dans la fabrication de biomatériaux, de dispositifs, d'articles ou d'implants, en particulier de dispositifs médicaux implantables à long terme dans les domaines de la cardiologie, de l'orthopédie, de la chirurgie plastique et de la gastroentérologie. Le procédé consiste en les étapes suivants: (a) traitement à la flamme d'une surface du silicone ou du matériau à base de silicone et (b) liaison du polyuréthane à la surface traitée à la flamme du silicone ou de la matière à base de silicone.
