摘要:In manufacturing a foamed plastics of a saturated polyester resin, in which asaturated polyester resin is melted in an extruder, a foaming agent is injected underpressure into the molten saturated polyester resin at an intermediate portion of a barrelof the extruder, and the molten saturated polyester resin containing the foaming agentis extruded from a die to manufacture the foamed plastics of the saturated polyesterresin, a polydimethylsiloxane having a boiling point, which is lower by at least 50° C. thanthe melting point of the saturated polyester resin to be foamed, at the atmosphericpressure is used as a foaming agent.
