Abstract

PURPOSE: To obtain the titled particle giving a molded product with excellent compression strength and dimensional stability, by charging an inorg. filler-contg. polyolefinic resin particle, a volatile foaming agent and water into a closed container and discharging the resulting product after heating under pressure.
CONSTITUTION: After, if necessary, a resin particle obtd. by compounding a polyolefinic resin such as polyethylene or an ethylene-propylene copolymer with an inorg. filler such as calcium carbonate is crosslinked, it is charged into a closed container together with a volatile foaming agent such as pentane or methyl chloride and water. The resin particle is impregnated with the foaming agent by heating to a temp. equal to or higher than the softening temp. of the resin particle, and then the container is held under a pressure equal to or higher than the vapor pressure of the foaming agent. The target particles of olefinic resin foam are obtd. by opening one end of the container and discharging the resin particles and water simultaneously to a lower-pressure atmosphere.
