Extrusion and expanded polystyrene(XPS) thermal insulation boards are made with polystyrene.Through special process,the hard expanded board is extruded.There is a sealed and foamed structure,which
is an environmental protection material with the performances of high-resist compression,waterproof,moistureproof,air proof,light weight,anti-corrosion,long service life and low conductivity factor
and so on. The thickness of the board is 20mm and the width is 1.2m.
