XPS is extruded polystyrene insulation board insulation board, the full name of extruded polystyrene foam insulation board, referred extruded sheet, also known as XPS board. Is a polystyrene resin combined with the polymer in the heated mixing, injection of the catalyst, and then extruded rigid foam board continuity of closed-cell foam, which is independent of the internal closed cell structure. XPS has a perfect closed cellular structure, which allows XPS board has very low water absorption (almost non-absorbent), low thermal conductivity coefficient, high pressure resistance, aging resistance (normal use almost no decomposition of the phenomenon of aging). Features: 1. insulation with high thermal resistance, low linear expansion lower than the characteristics of the structure of its closed-cell rate reached more than 99%, creating a vacuum layer to prevent the flow of cooling air, ensuring lasting and stable insulation performance of with respect to 80% of closed-cell polyurethane foam rate, leading edge self-evident. Practice has proved 20mm thick XPS extruded insulation board, the insulation effect is equivalent to 50mm thick polystyrene foam, 120mm thick cement perlite. Therefore, this material is the best choice for building insulation. 2. high compressive strength due to the special structure of the XPS board its high compressive strength, impact resistance strong, depending on the size and thickness of the compressive strength of XPS reach 150 ~ 500Kpa above, each system can withstand the load floor, Widely used in geothermal projects, highways, airport runways, the square ground, large cold storage insulation and interior decoration and other fields. 3. The water-repellent, moisture absorption is an important parameter to measure the insulation material. After absorbing insulation material insulation properties fall, at low temperatures, inhalation of water can easily freeze, destroy the structure of the insulation material, so that the compression plate and insulation performance decline. Because polystyrene molecular structure itself does not absorb water, plates stable molecular structure, no gap, solve the other material leakage, infiltration, frost, condensation and other issues. 4. The light texture, completely closed-cell foam XPS chemical structure and easy to use physical structure of honeycomb panels, it has the characteristics of lightweight, high strength, easy to cut, transport, and unbreakable, easy to install. 5. stability, corrosion resistance for a long time use, not aging, decomposition, does not produce harmful substances, the chemical properties of extremely stable and will not cause corrosion due to water absorption and degradation to performance degradation at high temperatures maintain their superior performance, according to the information, XPS extruded insulation board, even 30 to 40 years, can still maintain excellent performance, and does not decompose or mildew, no volatile toxic substances. 6. Product Environmental XPS board detected by the state departments from chemical stability, non-volatile harmful substances harmful to humans, the production of raw materials using environmentally friendly materials, do not produce any industrial pollution. This product is environmentally friendly building materials. Scope: 1, building roof insulation, steel roofing, building wall insulation, building ground moisture, the square ground, ground frost control, central air conditioning and ventilation pipes, etc. 2, ground moisture insulation, widely used in various moisture under the bottom of the building, the alpine highway, railway, airport runway embankment laying floor tiles can control the state of expansion and contraction, and has excellent load-bearing structure effect. 3, upholstery, advertising boards, widely used in interior decoration, ceiling, soundproof walls, doors sandwich filler material, heat insulation, sound insulation, moisture, weight and other effects. The plate in the production process added fire retardant, and therefore difficult to burn. Also can be widely used in advertising company produces a variety of advertising panels. Technical Specifications: thermal conductivity is only 0.028W / MK, good insulation and compression performance, compressive strength of up 220-500Kpa
