A silicone-based composition includes a silicone polymer and at least one acid neutralizer, wherein the silicone-based composition has a pH of at least about 5 after at least one dose of irradiation, when measured by a pH meter.

Silicone-based composition and article made therefrom

A tube can include a sidewall defining a lumen profile. The sidewall can include a plurality of alternating thin regions and thick regions. The lumen profile can include a plurality of alternating large radius and small radius regions. The thin regions or large radius regions can include elastic instabilities adapted to form an essentially complete closure of the lumen profile at minimal compression.

Peristaltic pump tube with non-uniform lumen profile

An assemblage including a silicone part; and a double-sided adhesive tape including a support tape, a first layer of a pressure-sensitive adhesive (PSA) on a first face of the support tape, a second layer of a PSA on a second face of the support tape, and where the silicone part and the double-sided adhesive tape are adhesively bonded to one another using a non-silicone-based structural adhesive.

Adhesive bonding process

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&#xb7;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.

Tube made of hydrophilized silicone

A process for forming an array of irregularities or features that are submicron-size in height and that have a characteristic lateral dimension that is micron- or submicron-size, over a surface of a material, by ion erosion, the process including: supplying the material with a thickness at least equal to 100 nm, the material being a solid hybrid material that includes: a simple oxide or a mixed oxide of one or more elements, an oxide molar percentage in the material being at least 40%; and a species, of a different nature to the one or more elements of the oxide, a molar percentage of the species in the material ranging from 6 mol % up to 50 mol % while remaining below the percentage of the oxide, most of the species having a largest characteristic dimension smaller than 50 nm, optionally heating the hybrid material before the erosion; structuring the surface of the hybrid material with an erosion that lasts less than one hour over an erosion area greater than 1 cm, until the array of features is formed, the structuring optionally being accompanied by heating of the hybrid material.

Method for structuring a surface by means of ion-beam etching, structured surface and uses

A process for forming an array of irregularities or features that are submicron-size in height and that have a characteristic lateral dimension that is micron- or submicron-size, over a surface of a material by reactive-ion etching, the process including: supplying the material with a thickness at least equal to 100 nm, the material being a solid hybrid material that includes: a simple silicon oxide or a mixed silicon oxide, most of the oxides in the case of a mixed oxide being silicon oxide, an oxide molar percentage in the material being at least 40%; and a species, of a different nature to the silicon of the oxide, a molar percentage of the species in the material ranging from 1 mol % or even up to 50 mol % while remaining below the percentage of the silicon oxide, at least most of the species having a largest characteristic dimension smaller than 50 nm, optionally heating the hybrid material before the etching; structuring the surface of the hybrid material, without masking, with etching that lasts less than 30 minutes over an etching area greater than 1 cm, until the array of features is formed, the structuring optionally being accompanied by heating of the hybrid material.
