- this heat storage composition 45 g was sampled, preheated at 200 ° C for 10 minutes using a 1 mm thick 20 cm square form, degassed, and then pressurized at 16 MPa a G for 2 minutes. It was cooled under a pressure of 10 MPa with a cooling press at room temperature to obtain a compression-molded article of the heat storage PP composition.
- a PET film which is usually used, was released from the mold, and lmm A1 plates were used above and below the mold.
- a heat storage material, a heat storage composition, and a film or sheet, a laminate, a molded article, a heat storage composite fiber, and a heat storage cloth member using the heat storage material, the heat storage composition, and the heat storage material that are easy to manufacture and have excellent heat storage properties can be provided.
