Extruded polystyrene board (XPS board) yog ib lub rooj tsavxwm ua npuas ncauj ua los ntawm polystyrene resin lossis nws cov copolymers, nrog rau lwm cov ntaub ntawv raw thiab cov khoom siv polymers. Cov sib tov yog rhuab thiab sib tov thaum lub catalyst yog txhaj, ces extruded thiab molded.
Nws cov qauv sab hauv yog kaw- cell honeycomb ua npuas ncauj qauv, nrog cov qauv sib xws thiab ntom ntom uas tsis sib cuam tshuam. Cov ntsuas kev ua haujlwm tseem ceeb suav nrog: thermal conductivity feem ntau ntawm 0.028-0.035 W / (m·K), compressive zog feem ntau ntawm 150-700 kPa, qhov ceev ntawm 25-45 kg / m³, thiab dej nqus feem ntau tsawg dua 1%.
