its application is mainly used for building wall, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration carving, etc.
If the EPS foam board is used in the external wall insulation system, its apparent density must meet the requirements of JG149-2003 “Expanded polystyrene board thin plaster external wall insulation system” standard, that is, the apparent density 18～22kg/m3.
Maintain the main layout of the building and extend the life of the building. Because external insulation puts the insulation layer on the outside of the layout, it reduces the stress caused by the layout deformation caused by temperature changes, and reduces the corrosion of the layout by harmful substances in the air and ultraviolet rays.
It is conducive to the stability of the room temperature, and the external wall insulation is used, because the wall heat storage can be arranged on the inner side of the wall, which is conducive to the stability of the room temperature.
Polystyrene materials are widely used in the construction and packaging industries due to their light weight, shock resistance, drop resistance, heat insulation, sound absorption, heat preservation, self-extinguishing, environmental protection and anti-aging, low cost, and easy construction.
When the expandable EPS beads are heated to above 90°C, the beads soften, and the vaporization of the blowing agent can expand the EPS beads by 40-80 times.
