Abstract
PURPOSE: To obtain the captioned item, by filling a thermosetting molding material containing a foaming agent in pressing molds, followed by pressing, releasing the pressure on the molds, and subsequently foaming and curing the material, so that the specific gravity, the thickness, and the multiplying rate of foaming of the item can be easily and optionally controlled.
CONSTITUTION: The thermoplastic material such as an unsaturated polyester resin molding material, etc. containing a foaming agent such as paratoluensulfonyl hydrazide, etc. preferably in an amount of 0.05W10% by weight, which, if necessary, is added with a reinforcement material such as glass fibers or the like, is filled in the pressing molds having a desired shape, and after pressing without substantial foaming and curing, the molds are slightly opened to release the pressure until a desired thickness is obtained, and at the time of the release of the pressure or thereafter the foaming and curing are allowed.
USE: For building materials, automobile parts, towers, tanks, etc.
