Method for the production of cellular plastic particles

Abstract

A method for preparing cellular plastic particles comprising the steps: providing a plastic material in the form of pre-expanded plastic material particles, loading of the pre-expanded plastic material particles with a blowing agent under the influence of pressure, expanding the pre-expanded plastic material particles loaded with a blowing agent for the production of cellular plastic particles, in particular cellular plastic particles with lower density, under the influence of temperature, wherein the expanding of the plastic material particles loaded with blowing agent under the influence of temperature is carried out by irradiating the plastic material particles loaded with blowing agent with high-energy thermal radiation, in particular infrared radiation.
