What are the characteristics of XPS foam board?
1 min read

XPS is extruded polystyrene, a sheet of expanded polystyrene used for insulation purposes. Generally, expanded polystyrene boards are called XPS boards. There are still EPS boards on the market, so how do we distinguish them? Therefore, the letter X was chosen to emphasize the extrusion process required for production. Other examples include XEPS (extruded expandable PS beads), XPET (extruded foam PET), etc.
XPS undergoes a continuous extrusion process in which physical blowing agents are injected into molten PS. The mixed PS, blowing agent and other additives are then cooled by the cooling extruder. As a result, a pressurized and viscous molten material is extruded through the slot die. As the material seeps out of the slot die, the pressure is released and the foaming process begins. The foam will go through the calibration system to take shape and form.
