Abstract

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 10mPa·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.
