The invention relates to a method for producing porous plastic pellets, comprising the following steps:-providing a plastic material in the form of pre-expanded plastic material pellets,-loading a blowing agent to the pre-expanded plastic material pellets under pressure,-expanding the pre-expanded plastic material pellets loaded with the blowing agent under the action of temperature, the invention relates to a method for producing porous plastic pellets, in particular porous plastic pellets having a lower density, in which the blowing-agent-loaded plastic pellets are expanded under the action of a temperature by irradiating the blowing-agent-loaded plastic pellets with high-energy thermal radiation, in particular infrared radiation. 本发明涉及一种生产多孔塑料颗粒的方法，包括以下步骤：-提供呈预膨胀塑料材料颗粒形式的塑料材料，-在压力下将发泡剂装载至该预膨胀塑料材料颗粒，-使装载有发泡剂的预膨胀塑料材料颗粒在温度的作用下膨胀，以生产多孔塑料颗粒，特别是具有较低密度的多孔塑料颗粒，其中通过用高能热辐射，特别是红外辐射照射该装载有发泡剂的塑料材料颗粒，使该装载有发泡剂的塑料材料颗粒在温度作用下膨胀。
