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.

To provide a foam-molded product which is light-weight and superior in formability, flexibility and shock absorbing capacity, and which exhibits favorable tactile impression and excellent safety, as well as a shock absorber using the same that provides favorable feel in wearing. Means for Resolution: When a foam-molded product is used which is produced by including foamed resin particles in a soft resin obtained from a silicone based polymer, as a base resin, produced by curing a liquid resin composition including: (A) a curing agent having at least two hydrosilyl groups in the molecular chain; (B) a polymer which has at least one alkenyl group in the molecular chain, comprises a saturated hydrocarbon unit or an oxyalkylene unit as a repeating unit that constitutes the main chain, and is a linear polymer having a number average molecular weight of no lower than 10,000; and (C) a hydrosilylation catalyst, the product can be suitably used in garments to which it is attached as a shock absorber at an appropriate site such as the front body, the flank part, the back body and the hip around the lumbar.

There is provided a self-supporting energy absorbing composite comprising: i) a solid foamed synthetic polymer matrix; ii) a polymer-based dilatant, different from i) distributed through the matrix and incorporated therein during manufacture of i); and iii) a fluid distributed through the matrix, the combination of matrix, dilatant and fluid being such that the composite is resiliently compressible. There is also provided a self-supporting energy absorbing composite comprising: iv) a solid, closed cell foam matrix; v) a polymer-based dilatant, different from i), distributed through the matrix; and vi) a fluid distributed through the matrix, the combination of matrix, dilatant and fluid being such that the composite is resiliently compressible.
摘要:
A thermoplastic resin foam, which is high in thickness-direction compressive strength and low in flexural modulus of elasticity, can be set pliably along a curved applicable portion such as body's outer surface, and can effectively absorb an impact force imparted from the outside; and an expandable thermoplastic resin molded product providing the above foam. An expandable thermoplastic resin molded product comprises an expandable thermoplastic resin sheet-form material of expandable thermoplastic resin having a sheet body and many projections formed scattered on at least one surface of the sheet body, and an elastic thermoplastic material layer laminated on at least one surface of the expandable thermoplastic resin sheet-form material so as to be spread over the outer surfaces of the projections; and a thermoplastic resin foam obtained by foaming the expandable thermoplastic resin molded product.
