Fiber-like or film-like moldings are produced from a plasticized mixture which, based on its weight, is composed of 60 to 10% by weight of a carrier component and 40 to 90% by weight of a phase change material wherein, based on the weight of the plasticized mixture, the carrier component contains 5 to 20% by weight of a polymer or polymer blend from the group comprising LDPE (low density polyethylene), HDPE (high density polyethylene), PMMA (polymethyl methacrylate), polycarbonate and mixtures thereof, 5 to 20% by weight of a styrene block copolymer and 0 to 20% by weight of one or more additives, and the phase change material is selected from the group comprising natural and synthetic paraffins, polyethylene glycol (= polyethylene oxide) and mixtures thereof, and the plasticized mixture is extruded through a spinneret or a slit die at a temperature of 130 to 220° C and is stretched. |
