Abstract: Provided is a vacuum thermal insulation material which is capable of maintaining a vacuum for a long period of time in a high temperature range. The present invention relates to a vacuum thermal insulation material which comprises a core material and an envelope in which the core material is sealed. The envelope comprises thermal fusion bonding layers, and the thermal fusion bonding layers that face each other at an end portion of the envelope are thermally fused to each other, thereby forming a sealed portion. The core material has a first main flat surface that is exposed to the relatively high temperature side when in use and a second main flat surface that faces the first main flat surface and is exposed to the relatively low temperature side when in use. At least a part of the sealed portion is arranged on the second main flat surface side.

Abstract: A composite molding material formed by kneading at least glass wool into a thermoplastic resin has such a feature that the glass wool in the composite molding material has a fiber diameter of 1 to 7 ?m, an average fiber length of 30 to 300 ?m, and an aspect ratio of not less than 10.

Abstract: A composite forming material of the present invention in which a fiberglass and a thermoplastic resin are compounded, where the fiberglass is a glass wool and a surface treatment is performed on the glass wool by spraying a solution which includes a silane coupling agent and/or a film former, a weight percent of the silane coupling agent to the glass wool is 0.24 wt %, and a weight percent of the film former to the glass wool is 2.4 wt %, the mean length of the glass wool is 600 ?m, and the diameter is 3.4 ?m.

Abstract: A method for producing a glass wool molded product includes the steps of processing a glass material into fibers so as to obtain a glass wool, gathering such glass wools to form a glass wool mat, and subjecting the glass wool mat to press molding, wherein the above described press molding is carried out, while supplying water so that the water content of the above described glass wool mat becomes 0.1% to 7.0% by mass, and while maintaining a temperature between 250° C. and 450° C.
