摘要:
A skin plate product is provided, which can be better tailored with respect to controlling the properties of the first and second surfaces by cutting holes in an adhesive matrix with a laser and subsequently filling these holes with a second material. Preferably at least one zone of the second material extends from the top surface to the bottom surface of the adhesive, with an exposed part of the second material at the top surface having a different pattern than an exposed part of the second material at the bottom surface. The zones are formed as bodies of frustums of cones having their basis at the same surface.
摘要:
An adhesive composition comprising a polymeric matrix and absorbent particles wherein at least a part of the absorbent particles are microcolloid particles. The microcolloid particles are water absorbent particles preferably having a rounded or spherical shape. The addition of microcolloids to an adhesive provides an improved moisture handling properties compared to state of the art technology as well as the rheological properties of the adhesive matrix may be less affected than by addition of traditional hydrocolloids.
摘要:
A substantially water-free, liquid, enzyme-containing composition comprises: (A) an enzyme; (B) a substance selected from (i) substances which in aqueous medium are substrates for said enzyme, (ii) substances which in aqueous medium are precursors for substrates for said enzyme, and (iii) substances which are cofactors for said enzyme; and (C) a non-aqueous liquid phase.
摘要:
A process for the conversion of sulphur dioxide contained in a feed gas to sulphur trioxide, comprising the steps of a) alternatingly providing a first feed gas containing a high concentration of sulphur dioxide and a second feed gas containing a low concentration of sulphur dioxide as a process gas, b) preheating the process gas by heat exchange with a heat exchange medium, c) reacting the process gas in the presence of a catalytically active material in a catalytic reaction zone, d) converting at least in part the sulphur dioxide of the process gas into sulphur trioxide contained in a product gas in the catalytic reaction zone, e) cooling the product gas by contact with a heat exchange medium, wherein a thermal buffer zone is provided in relation to one of said process steps, providing thermal energy produced during super-autothermal operation for heating the process gas during sub-autothermal operation.
摘要:
The invention relates to a method for assembling an adhesive device comprising a first matrix-forming material with holes and a second material, the method comprising: (a) compose the first matrix-forming material with holes; (b) compose the second material with a Tm lower than the Tm of the first material, while enabling increase in the Tm of the second material; (c) assemble the adhesive device by filling the holes of the first matrix-forming material of step (a) with the deformable second material of step (b) at a temperature where the second material is deformable and the first material is non-deformable; (d) increase the Tm of the second material.
摘要:
Accordingly, the present invention relates to a pressure sensitive adhesive composition consisting of a continuous phase comprising cross-linked polyalkyleneoxide polymer and a discontinuous phase comprising water absorbent hydrophilic agents wherein a) the water absorbent hydrophilic agent(s) is present in an amount between 1 and 40% w/w of the total adhesive composition; and b) the continuous phase comprises the reaction product (X) of: (i) a polyalkyleneoxide polymer having one or more unsaturated end groups, and where more than 90% w/w of the polyalkylene oxide polymer consist of polymerised alkyleneoxide moities having three or more carbon atoms, and (ii) an organosiloxane comprising one or more Si—H groups, carried out in the presence of an addition reaction catalyst. The present invention also relates to medical devices comprising such pressure sensitive adhesives.
