- Polypropylene [Idemitsu Kosan Co., Ltd., 2000 GP] was melt-pressed at 220 ° C. to form a 3 mm thick, 3 cm square plate.
- the heat storage material composition of the present invention suppresses decomposition and evaporation at high temperatures with little stickiness by using a side chain crystalline polymer as the heat storage material, and exudes.
- the heat storage material composition has a large heat capacity of melting with less refining, and has good workability, such as not being brittle even at the melting point or lower.
- a raw material of the heat storage material if a plurality of melting points are obtained by compounding a side chain crystalline polymer and a petroleum wax having a melting point (Tm) higher than that by 10 ° C or more, a plurality of melting points can be obtained based on the characteristics.
- Tm melting point
- the heat storage material composition of the present invention can be used for heating and keeping heat in buildings, bathtubs, bathrooms, dishes, hair curlers, textiles and cloths for clothes, interior materials such as steering wheels and dashboards of automobiles, and electronic materials. Used for materials, refrigerator inner walls, etc. to prevent sudden rise in temperature, and used for clothes, bedding, masks, and other protective equipment, etc. to remove heat from human body when touched. This gives the person a refreshing feeling and is useful as a material.
