欠点を有していた。Conventional molded facing materials are made by molding synthetic resin such as vinyl chloride into a hollow shape using rotation molding, blow molding, slash molding, etc. A frame is inserted into this molded facing material, and the frame and molded facing material are A solution of foamed synthetic resin such as urethane is injected between the
The desired interior product is obtained by foaming and curing. In addition, there are molded facing materials that use foamed synthetic resins such as foamed vinyl chloride to improve the feel and texture, but when the foaming ratio of the foamed synthetic resin is increased, the surface of the molded facing material becomes uneven and pinned due to air bubbles. Holes etc. were generated, the abrasion strength was significantly deteriorated, the foaming ratio could not be increased, and the color of the molded covering material was largely blurred.
