Patent number: 9752031Abstract: The invention relates to a process for the production of a piece made of silicone including: (a) the blending of 100 parts by weight of an HCR silicone base having a viscosity of greater than 106 mPa·s with from 0.3 to 7 parts by weight, such as from 0.5 to 5 parts by weight, of an amphiphilic copolymer including hydrophobic polydiorganosiloxane blocks and hydrophilic poly(ethylene oxide), poly(propylene oxide) or ethylene oxide and propylene oxide copolymer blocks, until a homogeneous blend of HCR base and amphiphilic copolymer is obtained, (b) the shaping of the homogeneous blend obtained, and (c) the curing of the shaped blend by heating or irradiation. It also relates to a piece, in particular a tube, manufactured according to this process and to a device comprising such a tube.Type: GrantFiled: October 7, 2014Date of Patent: September 5, 2017Assignee: SAINT-GOBAIN PERFORMANCE PLASTICS FRANCEInventors: Alban Letailleur, Boris Jaffrennou, Christophe Le Baron

Publication number: 20170129209Abstract: An adhesive bonding process can include: treating at least one region of the surface of a silicone part so as to increase the surface energy of the region treated; providing a double-sided adhesive tape comprising a support tape, a first layer of a pressure-sensitive adhesive (PSA) on a first face of the support tape and a second layer of a PSA on a second face of the support tape, applying a non-silicone-based structural adhesive to the treated region of the surface of the silicone part and/or to the first PSA layer, bringing the treated region of the surface of the silicone part into contact with the first PSA layer, and curing the non-silicone-based structural adhesive. An assemblage can be obtained by such a process.Type: ApplicationFiled: November 10, 2016Publication date: May 11, 2017Inventors: Hadrien HEUCLIN, Alban LETAILLEUR
