XPS foamed board, also named as polystyrene extrusion plastic board(XPS for short) has a perfec closedpore

alveolate structure. Its density, water absorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other board heat preservasion materials and they have the characteristics
of strong intensity, light material, airtight, anticorrosion, aning resistance, low cost ,etc.It has been widely used
in the fields of heat preservation and heat insulation in the construction industry, frost resistance of the highway,
railway, airport, square and household fitment.It is the generally acknowledged and the best heat preservation
material in the market at present.
For heat preservation of steel construction workshop, iron sheet house and colored ripple tile;
For making up the heat insulation board in the refrigeration storehouse for cold preservation and waterproofing;
For laying the bedding under the road bed of the highway for buffering and controlling the frost heaving of the ground;
For waterproofing and heat preservation of residential building, office building, the factory wall and roof;
For laying the bedding under the floor for the functions of heat insulation, dampproof and sound insulation;
