Introduction to EPS Pre – expander
EPS (Expandable Polystyrene) pre – expander is a crucial piece of equipment in the EPS processing industry. It is used to expand raw EPS beads into pre – expanded beads with a certain expansion ratio. These pre – expanded beads are then used in various applications, such as packaging materials, insulation boards for construction, and lightweight filling materials. The pre – expansion process involves heating the EPS beads with steam in a closed chamber, causing the blowing agent inside the beads to vaporize and expand the beads. The quality and performance of the EPS pre – expander directly affect the quality of the pre – expanded beads and the final products. EPS Pre-expander
