Low internal stress technology (SOHO core patent) is the use of multiple foaming equipment for multiple foaming of materials, so that fluorine-free, bromin-free low internal stress extrusion (XPS) extruded polystyrene board to achieve 100% perfect foaming, its dimensional stability than the traditional extrusion board more than double, the closed-cell extruded polystyrene foam can be made. The technology to overcome the world decades of unsolved extrusion board dimensional stability aging instability problem, Deformation, cracking, falling off and other drawbacks will not be repeated.
