Microcapsule, useful as additive in a composite, comprises a solid carrier material for an auxiliary- and/or active-substance and a wall material encapsulating the carrier material

摘要

Microcapsule (5) comprises at least one solid carrier material (1) for at least one auxiliary- and/or active-substance (2) and at least one wall material (4) encapsulating the carrier material, where the carrier material is loaded with the auxiliary- and/or active-substance. Independent claims are included for: (1) a composite comprising a matrix material (preferably a thermoplastic polymer) and the above microcapsule, as additive, distributed in the matrix material; (2) a method for preparing the composite from a thermoplastic polymer and the microcapsule, as additive, comprising mixing the polymer with the microcapsule by melt mixing in a mixing and/or extruding device to form the composite; and (3) intermediate or final product obtained by extruding, injection molding, blow molding, calendering, deep-drawing and/or pressing the composite.
