摘要： The present invention solves the problem of realizing a lighter cushion body that has ample cushioning properties when a person sits or lies thereon by: providing a plurality of rod-shaped or flat plate-shaped support bodies (2) comprising a synthetic resin foam that has a bending deflection amount of 20 mm or more as measured according to the method described in JIS K7221-2:2006 and a pressing force of 2-100 N at 20 mm of deflection, and legs (3) on which the support bodies (2) are placed or fixed; using the support bodies and the legs to form a space (5) that makes it possible to bend and deform the support bodies; and arranging the plurality of rod-shaped or flat plate-shaped support bodies (2) in a row so as to be deformable.

摘要： A foamed body produced by using expandable particles, and having communicating pores has sound absorption characteristics, and can be used as a sound absorptive material. However, a sound absorptive material comprising such a foamed body could not attain a high sound absorbing coefficient in a wide acoustic frequency band. The subject mold body is produced by using resin particles and has sound absorption characteristics, the resin particles having through pores and a porosity in a most densely packed state of 45-80 %. The void ratio of the molded body is 10-60 %, and the bulk density thereof 0.01-0.6 g/cm . The molded body has not less than 3 continuous central frequency measuring points at which the sound absorbing coefficient is not less than 70 %, and not less than 7 continuous central frequency measuring points at which the sound absorbing coefficient is not less than 50 % in the sound absorbing coefficients at the central frequencies of 250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500 and 3150 (Hz) which are determined by a sound absorbing coefficient measuring method according to the reverberation method under JIS A1409.

摘要： Foamed particles of cross-linked aliphatic polyester resins having a gel fraction of at least 5 % by weight. The foamed particles can be obtained by cross-linking non-cross-linked aliphatic polyester resin particles with a cross-linking agent containing an organic peroxide to obtain cross-linked resin particles having a gel fraction of at least 5 % by weight, and foaming the cross-linked resin particles. Biodegradable foamed moldings are obtained by thermally foaming the foamed cross-linked aliphatic polyester resin particles in a mold.

摘要： The present invention relates to a vehicle seat back which comprises a seat back pad. An opening portion is disposed at a front portion of the seat back pad where a backrest surface is formed for a seated person. A plurality of independent rod-like or plate-like supports, which are formed of a synthetic resin foam having a bending deflection measured according to a method described in JIS K7221-2:2006 of at least 20 mm and having a load at a 20 mm deflection of between 2 N and 100 N, are fixed to a seat frame or a circumferential edge portion of the opening portion, or integrally molded with the circumferential edge portion of the opening portion, in a bridging direction between opposing edge portions forming the opening portion and in the form of a single-point support or multi-point support. The seat pad is a structure which has a shape in which the plurality of supports are arrayed at predetermined intervals. The vehicle seat back of the present invention comprises a void portion which enables bending deformation of the support toward a rear portion of the support, and therefore weight can be reduced, and cushioning properties, fit, and recyclability can be improved.

摘要： A polycarbonate resin foam having a density D of 0.6g/cm3 or less, and also having a value of E¿80?/D which is obtained by dividing an energy absorbance at 50 % compression at 80 °C, E80 kg.cm/cm?3¿, by the density of the foam, of 30 (kg.cm/cm?3)/(g/cm3¿) or more. A shock absorber for a vehicle comprises a core made of this resin foam and a skin covering the surface of the core.
