PHASE CHANGE MATERIAL

This invention describes a phase change material being 1,3-propanediol ester where the 1,3-propanediol ester can be either a 1,3-propanediol monoester or a 1,3-propanediol diester. This invention further describes the use of 1,3-propanediol ester as a phase change material for releasing or absorbing latent heat during melting or crystallization. This invention also describes the use of the phase change material for use in non-food and food applications.
