Abstract
A stampable sheet shaped-product has a skin layer consisting essentially of a foamable thermosetting resin and formed on and in one or both of surfaces of a sheet-like open cell plastic foam. Optionally, a facing material layer of a proper material may be formed on one or both of surfaces of the skin layer. Such stampable sheet shaped-product is produced by applying a composition consisting essentially of a foamable thermosetting resin onto one or both of surfaces of a sheet-like open cell plastic foam, so that the one or both surfaces is or are impregnated with the composition. Optionally, a proper facing material is placed on one or both of the surfaces, and the resulting material is subjected to a hot pressing. Alternatively, the stampable sheet shaped-product may be produced by a process including a thermal treatment step interposed between the above-described applying and hot-pressing steps.
