XPS foam board is an extruded polystyrene insulation manufactured through a plastic extrusion process. 1.XPS foam board: 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 board Density Kg/m3 36 40 Thermal conductivity, 90 days, 10°C W/mK 0.027 0.03 Compressive strength at 10% deflection or yield, (vertical) kPa ≥300 Tensile strength kPa ≥300 Water absorption Vol-% <=1.00% Capillarity nil nil Coefficient of linear thermal expansion mm/mK 0.07 Temperature limits °C -50°C, +75°C 2.2main characteristics of XPS foam board Stable performance and anti-aging: The extruded polystyrene (XPS) insulation boards can be used 35-50 years. 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 loads Water resistance: Polyfoam is almost 100% closed cell and as such is unaffected by moisture Lightweight: volume optimization and easy to handle Resistance to deformation Resistance to impact 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 friendly Recyclable: Polyfoam can be 100% recyclied
