XPS is extruded polystyrene insulation board insulation board, the full name of extruded polystyrene foam insulation board, referred to as extruded sheet, also known as XPS board. Is supplemented with polystyrene resin polymer heated while mixing, into the catalyst, then squeeze out the rigid foam board continuity of closed-cell foam, which is inside a separate closed bubble structure. XPS has a perfect closed cellular structure, which allows XPS board has very low water absorption (almost non-absorbent), low thermal conductivity, high compressive resistance, aging resistance (normal use almost no aging decomposition phenomenon). Features: 1. insulation with high thermal resistance, low linear expansion lower than the characteristics of its structure obturator rate reached more than 99%, forming a vacuum layer to prevent the flow of cooling air, to ensure lasting and stable insulation performance of with respect to 80% of closed-cell polyurethane foam rate, leading edge self-evident. Proven 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. Due to the special structure of high compressive strength of XPS boards, high compressive strength, impact resistance strong, depending on the size and thickness of XPS of its compressive strength reaches 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 materials. After absorbing insulation material insulation properties fall, at lower 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, sheet molecular structural stability, without gaps, solve the leakage of other materials, penetration, frost, condensation and other issues. The light texture, completely closed-cell foam chemical structure and easy to use XPS panels of honeycomb physical structure, it has the characteristics of light weight, high strength, easy to cut, transport, and difficult to damage, easy installation. 5. stability, good corrosion resistance for a long time use, not aging, decomposition, no harmful substances, the chemical properties of extremely stable and will not cause corrosion due to water absorption and degradation to performance degradation in high temperature environments can still maintain its superior performance, according to the information, XPS extruded insulation board even with 30 to 40 years, can still maintain excellent performance, and will not decompose or mildew, no volatile toxic substances. 6. Product Environmental XPS board detected by the national authorities from chemically stable, non-volatile harmful substances, harmful to humans, the production of raw materials using environmentally friendly materials, do not produce any industrial pollution. The product is environmentally friendly building materials. Scope: 1, building roof insulation, steel roofing, building wall insulation, building ground moisture, the square ground, ground frost heave control, central air conditioning and ventilation pipes, etc. 2, the ground moisture insulation, widely used in various moisture under the bottom of the building, alpine highway, railway, airport runway embankment laying floor tiles can control the state of expansion and contraction, and with excellent load-bearing structure effect. 3, interior decoration, advertising board, widely used in interior decoration, ceiling, noise walls, door sandwich filling material, heat insulation, sound insulation, moisture, weight and other effects. The board added in the production process of the fire retardant, it is not easy to burn. Also can be widely used in advertising company produced all kinds of advertising boards. Specifications: thermal conductivity is only 0.028W / MK, good heat and compression performance, compressive strength of up 220-500Kpa Shen Yang-Ming Hui of insulation materials Limited production of Jufu brand extruded polystyrene foam (XPS for short ) insulation board, honey has a closed-cell structure, density of the product, water absorption, thermal conductivity and vapor permeability coefficient of less than King's type heat insulation materials. Therefore, with good intensity, light material, airtight, corrosion-resistant, anti-aging, low prices, known as the insulation material in the little prince. Widely used in building wall insulation, roof insulation, foundation backfill insulation, cold storage, refrigerated trucks, road, airport runways, tunnels and other noise insulation.
