A single disinfectable vinyl baby bouncer seat cover is made from health care use vinyl. The specifications of the health care vinyl permit surface disinfection using sodium hypochlorite (bleach) 1:10 diluted with water. A baby bouncer seat cover constructed from health care use vinyl allows disinfection in infection controlled environments using surface disinfectants containing sodium hypochlorite (bleach) 1:10 diluted with water. The disinfectable vinyl baby bouncer seat cover incorporates a seat belt restraint system and the design creates a central pocket that cradles an infant in a semi-reclined position. The design and health care use vinyl components incorporated in the invention, create a comfortable infant seat cover that maximizes disinfection within infection controlled environments. The disinfectable vinyl baby bouncer seat cover is placed over a baby bouncer frame, the baby bouncer frame is not inclusive in this invention. Environments such as hospital nurseries, neonatal intensive care units, pediatric intensive care units, pediatric units, large day care centers, and any other institutions that serve large numbers of infants may disinfect the seat covers after each use maintaining an environment of infection control.

Methods and combinations for making and using one or more thermally conductive cellular foam layers comprising flexible cellular foam and metallic material particulates, and said thermally-conductive cellular foam layers may be located on, under, or in cushioning foams and mattresses or placed between on, under, within, or between other layering substrates to increase the overall cooling capability of the composite. The thermally conductive foam may be used in mattresses, pillows, bedding products, medical cushioning foams, and similar materials used in bedding environments.

Described are acoustic absorber materials with high acoustic attenuation and high thermal conductivity comprising an inorganic, porous foam and an absorbing material within at least a portion of the pores of the foam, ultrasound transducers and devices including the same, as well as methods of making the materials.

A method for producing polypropylene-based resin expanded beads includes dispersion, blowing agent impregnation, and foaming steps. Beads used in the dispersion step include a core layer having a polypropylene-based resin as a base material resin, and a fusion-bonding layer covering core layer; the beads fusion-bonding layer includes carbon black and a NOR-type hindered amine; a carbon black blending ratio is adjusted to 0.5 wt % or more and 5 wt % or less; and an amine blending ratio of the beads is adjusted to 0.03 wt % or more and 0.5 wt % or less; the polypropylene-based resin expanded beads have a surface on which a fusion-bonding layer is located; the fusion-bonding layer includes the carbon black and hindered amine; a carbon black blending ratio is 0.5 wt % or more and 5 wt % or less; and a blending ratio of the hindered amine is 0.03 wt % or more and 0.5 wt % or less.
