Extrusion polymerization benzene ethylene （ XPS) Insulation board , with polyphenyl Vinyl resin As the main raw material, the hard material is continuously extruded and foamed through special process board 。 It has a unique and intact closed cell honeycomb structure, and has high-quality environment-friendly materials that are resistant to high pressure, moisture, air permeability, water absorption, corrosion, low thermal conductivity, light weight, and long service life. XPS Plastic extruded board Pipe cooker is used for wall insulation, plane concrete roof and steel structure roof insulation, low-temperature storage ground, parking platform, airport runway, expressway and other fields of moisture-proof insulation, ground frost heave control, and is currently a cheap and high-quality heat insulation and moisture-proof material in the construction industry.
1. Excellent thermal insulation
It has the characteristics of high thermal resistance, low linearity and low expansion ratio, and its closed porosity reaches Above 99%, a vacuum layer is formed to avoid air flow and heat dissipation, and ensure good and stable thermal insulation performance. It is self-evident that the closed cell ratio of polyurethane foam is 80%. Practice has proved that 20mm thick XPS extruded insulation board Its thermal insulation is equivalent to 50mm thick foamed polystyrene, 120mm thick cement perlite. Therefore, this material is used for building thermal insulation Better choice 。
2. Compressive resistance of
because Xps flame retardant extruded board Vacuum closed cell structure, so its compressive strength is very high, and its impact resistance is relatively good. According to Xps flame-retardant extruded plate has different models, thicknesses, unit weights and other specifications. Its compressive strength is more than 220-500kpa, and can withstand various ground loads. It is used in geothermal floor heating plates, highways, airport runways, square floors, and large refrigerators and other fields.
3、 Light texture, easy to use
The completely closed cell foaming chemical structure and cellular physical structure of XPS board make it light and high, easy to cut, transport, not easy to damage, and easy to install.
4、 Good stability and corrosion resistance
During long-term use, it does not age, decompose or produce harmful substances. Its chemical performance is more stable than it is. It will not degrade due to water absorption and corrosion, which will reduce its performance. It can still maintain its superior performance under high temperature environment. According to relevant data, it is produced by large domestic factories XPS extruded insulation board has a service life of about 60 years, and can still maintain good performance, without decomposition or mildew, and without the volatilization of toxic substances.
