PURPOSE:To provide a heat-accumulation material containing a polyalkylene glycol ether, having prolonged warm-keeping period, having excellent heat- reserving property, usable over a long period without causing the phase- separation and lowering of the performance and useful for heat-reserving, air conditioning, etc. CONSTITUTION:The objective heat-accumulation material contains a polyalkylene glycol ether preferably composed of a polyethylene glycol ether, etc., of formula [R and R' are H, alkyl or alkenyl (R and R' are not H at the same time); n is >=10]. The material preferably further contains an antioxidant and a thermal conductivity improving agent. |
