Polystyrene foam board, also known as foam board or EPS board, is used as a protective layer for waterproofing. It is made from expandable polystyrene beads containing a volatile liquid foaming agent. After pre-expansion by heating, it is molded into a white solid with a fine closed-cell structure.
SOHO polystyrene insulation board includes ordinary polystyrene insulation board and graphite polystyrene insulation board. The insulation boards are made using imported equipment from South Korea, advanced European technology, and imported raw materials. The boards do not contain chlorofluorocarbons or hydrochlorofluorocarbons, which not only extend the insulation life of buildings but also help reduce CO2 emissions.
Main uses: The type of EPS SIP panel and EPS sandwich panel are widely used for building wall and roof insulation, as well as for the insulation layer of composite insulation boards. It is also used as insulation material for vehicles, ships, refrigeration equipment, and cold storage warehouses, and for decorating and sculpting various models.
