Coarse-particle microcapsule preparation

摘要

The present invention relates to a coarsely divided microcapsule preparation with particles whose particle sizes are in the range from 200 μm to 5 cm, comprising microcapsules with a capsule core of latent heat storage material and a thermosetting polymer as capsule wall and one or more polymeric binders whose binder polymer has thermoplastic properties and film-forming properties under processing conditions, where the binder content, calculated as solid, is 1-30% by weight, based on the total weight of the coarsely divided microcapsule preparation.
