Profile:
XPs / Extrusion board through a special process for forming foam sheet extrusion, which formed on the surface of the dura mater uniform formation, internal obturator completely continuous uniform foam was honeycomb structure, and therefore high pressure, light, non-absorbent, airtight, resistant, non-biodegradable properties. Polystyrene foam board with EPS compared to its strength, insulation, anti-moisture penetration, such as improved performance. Conditions in the water can still maintain its integrity and insulation performance and compressive strength, especially suitable for building insulation, moisture-proof processing, today's construction industry and inexpensive construction materials.
Characteristics:
Light high hardness of the product as a result of an extremely special structure, which meant a complete closure of the obturator foam cell formation of lightweight, honeycomb-like structure of uniform strength, Therefore, the plate is very convenient for transportation, but also easy to cut, fixed simple. Excellent thermal insulation of the product with high thermal resistance, low linear expansion properties, is a good thermal insulation material. Its thermal conductivity is only 0.029W/mk, and 70 percent relative humidity in the next several years, can maintain its low thermal conductivity, it generally applies to apartments, the building, plant, such as thermal insulation of buildings can reduce consumption of natural resources and increase the living comfort. High compressive strength because of its structure are thick cell wall and intramural closely linked seamless, so its very high compressive strength up to more than 250KPa, but also In the 24 hours of immersion has remained unchanged, it is other material, including expanded polystyrene EPS by less than performance. Even be used as a manned or parking platform can meet the requirements. Very low water absorption the product with full obturator structure, positive and negative do not have the cracks, so that leaking boat cold and frozen / thaw cycle, such as the situation arising from the wet gas can not be thoroughly Caojing, low water absorption, so that the performance of plate can be achieved sustained and steady play. Contingent excellent effect of anti-wet moisture Friends products can effectively block the infiltration of geogas, in high-temperature circumstances, can effectively produce the effect of moisture. In addition, moisture-proof floor with a dry internal block structures to protect the building from moisture damage. Low cost using XPS Extrusion board, will enable the construction costs have greatly lowered, and the processing and transportation are very convenient, the indirect cost was also low.

Typical Applications
Apply to reinforced concrete roof, pressure-type copper roofing, parking is inverted roofing insulation roofing insulation layer the material of choice, using this product for the laying of insulation layer above the waterproof layer, will enable the waterproof layer from the temperature, ultraviolet, external damage to the roof and saved the exhaust system. , The external wall insulation apply to the building's surface, the external wall insulation also applies to low-temperature cold storage, refrigerated trucks, etc., and has a very excellent effect of load-bearing structure. Ground insulation alpine region highway, railway, airport runway under the road surface and laying of Subgrade control the situation of the ground frost heave. Floating floor filled with the laying of broad application of sub-Chatham boards, parquet flooring, such as the laying of floating filling laying, at the same time and use of noise insulation from moisture. Concrete pouring of the permanent or temporary template
