Abstract:
Provided are a heat-insulating film and a heat-insulating film structure with improved heat insulating effects. Also provided are a porous plate-shaped filler included in the heat-insulating film and a coating composition for forming the heat-insulating film. In a heat-insulating film of the present invention, porous plate-shaped fillers are dispersedly arranged in a matrix for binding the porous plate-shaped fillers. In the heat-insulating film, the porous plate-shaped fillers are preferred to be arranged (stacked) in a layered state. The porous plate-shaped filler is a plate with an aspect ratio of 3 or more, and has a minimum length of 0.1 to 50 μm and a porosity of 20 to 99%. The heat-insulating film using the porous plate-shaped fillers ensures a longer length of heat transfer path compared with the case where spherical or cubic fillers are used. Accordingly, the thermal conductivity can be reduced.

Abstract:
A thermoplastic composition is described that can be directly coated with a metal according to a metallization process with no intervening base coat formation process necessary. The thermoplastic composition includes a polyarylene sulfide and a filler having a selectively controlled average length and aspect ratio. Molded articles formed of the thermoplastic composition can have an ultra-smooth surface so as to directly accept a metallization coating.
