PURPOSE:To provide a heat accumulating body making use of latent heat, having high crystallization temperature, capable of being used at high temperature, not to be swelled in accumulating of heat, and capable of preventing the mutual fixing and the lumping even if any special coating is not applied on the front surface. CONSTITUTION:Since materials wherein degradation inhibitor and cross linking assistant are respectively added to any one of polyacetal copolymer, polyacetal homopolymer, poly-fluoride polymer, 11 nylon polymer, 12 nylon polymer and ethylene vinyl alcohol copolymer at a rate of 20 pts.wt. or less, the crystallization temperature is increased by 25 to 50 deg.C in comparison with the conventional heat accumulating body using high density polyethylene. |
