1.Wall insulation board(XPS) XPS is an extruded polystyrene insulation manufactured through a plastic extrusion process. The resulting boards are almost 100% closed cell, strong, highly moisture resistant and easy to cut and shape.XPS is particularly indicated for places where a high mechanic resistance is required. Its resistance to water and compression make it the ideal insulation solution for extreme conditions. Moreover, it is very easy to install and offers a high performance thermal insulation for your building. XPS foam board widely used in wall insulation, low-temperature storage facilities, parking platform, the airport runway, construction of concrete roof and the structure of the roof, highways and other areas of moisture-proof inexpensive decoration industry Material.2.1 Technical data sheet of the XPS foam boardDensityKg/m338 40Thermal conductivity, 90 days, 10°CW/mK0.027 0.03Compressive strength at 10% deflection or yield, (vertical)kPa≥300Tensile strengthkPa≥300Water absorptionVol-%<=1.00%CapillaritynilnilCoefficient of linear thermal expansionmm/mK0.07Temperature limits°C-50°C, +75°C2.2main characteristics of XPS foam board1. Stable performance and anti-aging: The extruded polystyrene (XPS) insulation boards can be used 35-50 years2. Resistance to compression: compared with other thermal insulation material(200Kpa for EPS), it has better compressive strength(around 300Kpa), which make it the ideal solution for heavy domestic or industrial loads3. Water resistance: Polyfoam is almost 100% closed cell and as such is unaffected by moisture4. Lightweight: volume optimization and easy to handle5. Resistance to deformation6. Resistance to impact7. Versatile: the closed cell structure and density of Polyfoam allow specific edge details and surface finishes to be cut into the boards to make them as fit for the job as possible. Moreover, Polyfoam can be cut into almost any shape 100% ozone friendly8. Recyclable: Polyfoam can be 100% recyclied.
