Abstract
The present invention relates to a first low-temperature insulating material which comprises polyvinyl chloride, a plasticizer, a water-containing or absorbing gel or an aqueous solution of a water-soluble polymer and an emulsifier and a second low-temperature insulating material which comprises polyvinyl chloride gelled by mixing with a plasticizer and a surface-covered, water-containing hydrogel. The insulating materials are inexpensive and show excellent heat-insulating properties and excellent flexibility at low temperatures.
