Patent ID: 8828530

Claim:
A process for producing fibrous or foil-like moldings made of a plastified mixture which is comprised, based on its weight, of from 60 to 10% by weight of a carrier component and from 40 to 90% by weight of a phase change material, the carrier component comprising from 5 to 20% by weight of a polymer or polymer blend from the group of LDPE, HDPE, PMMA, polycarbonate, or mixtures thereof, from 5 to 20% by weight of a styrene block copolymer, and from 0 to 20% by weight of one or more additives, and the phase change material has been selected from the group consisting of natural and synthetic paraffins, long-chain dialkyl ethers, long-chain alkyl alcohols, low-molecular-weight highly crystalline PE waxes, polyethylene glycol, and mixtures thereof, said process comprising extruding the plastified mixture at a temperature of from 130 to 220° C. through an extrusion die to give fibrous or foil-like moldings, and quenching the extruded moldings within a period of from 0.05 to 4 s after discharge from the extrusion die to a temperature in the range from 10 to 80° C.
