According to the present invention, a sealing material for a high-pressure hydrogen container, which mainly comprises a silicone rubber composed of a dimethyl siloxane segment, a methyl vinyl siloxane segment, and a diphenyl siloxane segment, and a high-pressure hydrogen container using the sealing material are provided. In order to seal a high-pressure hydrogen container (CHG tank) system for fuel cell vehicles with an elastomer, the elastomer has (1): excellent durability in a variable pressure environment of high-pressure hydrogen; and (2): excellent sag resistance in low-temperature to high-temperature environments, and thus the significant technical objectives (1) and (2) have been achieved.

A molded component for the beam path of a radar apparatus with low radio transmission loss and improved hardness and abrasion resistance is provided. The molded component for the beam path of the radar apparatus comprises a base bodycomposed of a resin layer, and a bright decoration layerdisposed on the surface of the base body, the bright decoration layer being composed of tin and/or a tin alloy.

Molded component for beam path of radar apparatus

A molded component for the beam path of a radar apparatus with a low radio transmission loss and improved hardness and abrasion resistance is provided. The molded component for the beam path of a radar apparatus comprises a base bodycomposed of a cyclic polyolefin resin layer, and a bright decoration layerdisposed on the surface of the base body. Preferably, by disposing a modified layertreated by plasma ion etching and/or highly concentrated ozone water especially on the surface of the cyclic polyolefin resin, wettability on the surface is improved, thereby substantially improving the adhesion to the bright decoration layer.

This invention provides a bright decorative molded article exhibiting a bright color, and particularly a gold color tone. Also, this invention provides a molded article located in the beam path of a radar device that allows only a small radio transmission loss. This bright decorative molded article comprises: an opaque resin substrate; a light-emitting device provided thereon; a transparent resin layer covering the substrate and the light-emitting device; a bright decorative layer (upper surface layer) covering the light-emitting device on the transparent resin layer; and a bright decorative layer (lower surface layer) provided on the surface of the substrate at a portion covered by the bright decorative layer (upper surface layer). Alternatively, a bright decorative molded article comprises: an opaque resin substrate; a light-emitting device provided thereon; a transparent resin layer covering the substrate and the light-emitting device; and a bright decorative layer (lower surface layer) covering part of the surface of the substrate.
