The beads are then permeated which has a "blowing agent", a material that enables the beads to become expanded. Pentane is commonly used as being the blowing agent. The beads are additional to the constantly agitated reactor With all the blowing agent, between other additives, as well as the blowing agent ทำSEO seeps into pores inside of Every bead. The beads are then expanded utilizing steam.[forty eight]
