SHAPE FORMABLE POLYURETHANE FOAM PRODUCT HAVING SHAPE MEMORY PROPERTIES, METHOD OF USING THE SAME AND CUSHION MATERIAL TO BE WORN ON HUMAN BODY

摘要

It is intended to provide a foamed resin product having shape-formable properties, a method of using the same and a cushion material that is to be worn by the human body. The foamed resin product (a foamed flexible polyurethane product, etc.) having shape-formable properties as described above is characterized by having a glass transition temperature, that is expressed as the temperature of the loss tangent peak, of 10°C to 35°C, a loss tangent within this temperature range of 0.20 to 0.80, and, with respect to the storage elastic modulus (G') within this temperature range, the ratio (G' max /G' min ) of the maximum value (G' max ) to the minimum value (G' min ) of 3.0 to 30. The method of using the same as described above is characterized by comprising attaching a molded article made of the foamed resin product having shape-formable properties to the body surface of the human body, and lowering the hardness of the molded article due to the heat transferred from the human body so as to deform the molded article by allowing to follow-up the shape of the body surface. The cushion material to be worn by the human body as described above is characterized by comprising a molded article made of a foamed resin product having shape-formable properties.
