XPS Extruded Polystyrene

The full name of XPS (extruded polystyrene) is Extruded Polystyrene Foam Board.

It is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polymers, heated and mixed while injecting the catalyst, and then extruded and molded. Its scientific name is Xps Extruded Polystyrene Foam Insulation Board (XPS for short). XPS has a perfect closed-cell honeycomb structure. This structure allows XPS boards to have extremely low water absorption (almost no water absorption), low thermal conductivity, high compression resistance, and aging resistance ( There is almost no aging decomposition phenomenon under normal use).
