Abstract: A foamed styrene resin material has a density .rho. of 0.02 to 0.008 and a melt tension of the styrene resin of 5 to 40 gf. The relation between an average cell diameter d (.rho.m) and the density .rho. is given by the expression: and a relation between a thermal conductivity .lambda. (kcal/m.cndot.h.cndot. .degree.C) and the density .rho. given by the expression: Accordingly, the foamed styrene resin material has a low thermal conductivity and excellent insulating property in spite of a low density (high expansion ratio foam) thereof.

Abstract: The present invention provides a process for producing a molded foam article of a crystalline aromatic polyester resin. The process is characterized by heating the surface temperature of a mold for cavity-molding to the temperature within a range of from ( Tg + 35 ) to ( Tg + 57 ) DEG C (Tg is a glass transition temperature of the crystalline aromatic polyester resin prepuffs), thereby tomoldprepuffs, and cooling the surface of the mold to a temperature not lowered than Tg for at least 20 seconds.

Abstract: A method for producing a foamed-in-mold product which is characterized as comprising heating the surface of a foaming mold to a temperature of (Tg+35) ~C to (Tg+57)~C, wherein Tg represents the glass transition temperature of pre- foamed particles of an aromatic polyester resin charged in the mold, to perform a foam molding in the mold of the pre-foamed particles and then, conducting a slow cooling of the surface of the foaming mold to a temperatur e not lower than Tg over a period of 20 seconds or more while holding the foam ed product in the mold as it is. The method can be used for producing a foamed- in- mold product which exhibits satisfactory fusion bonding, excellent dimension al stability, and in some cases, also good appearance, and thus is suitable for use in industrial and automobile parts and the like.
