1、优良的保温隔热性

　　1, excellent insulation

　　石墨挤塑板具有高热阻、低线性、膨胀比低的特点，其结构的闭孔率达到了99%以上，形成真空层，避免空气流动散热，确保其保温性能的持久和稳定，相对于发泡聚氨酯80%的闭孔率，领先优势不言而喻。实践证明20mm厚的XPS挤塑保温板，其保温效果相当于50mm厚发泡聚苯乙烯，120mm厚水泥珍珠岩。

　　Graphite extruded plate with high thermal resistance and low linear expansion ratio, the characteristics of the low, the obturator structure rate reached more than 99%, the formation of a vacuum layer, avoid air flow cooling, to ensure that the insulation performance of lasting and stable, relative to the closed cell foam polyurethane rate of 80%, the leading advantage is self-evident. Practice has proved that the insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick foamed polystyrene and 120mm thick cement perlite.

　　2、卓越的高强度抗压性

　　2, excellent high strength compressive resistance

　　由于XPS板的特殊结构，其抗压强度极高、抗冲击性极强，根据XPS的不同型号及厚度其抗压强度达到150～500Kpa以上，能承受各系统地面荷载，石墨挤塑板广泛应用于地热工程、高速公路、机场跑道、广场地面、大型冷库及车内装饰保温等领域。

　　Because of the special structure of XPS board, its high compressive strength, impact resistance is strong, according to different sizes and thickness of XPS its compressive strength reached 150 ~ 500Kpa above the ground, can withstand the load of each system, graphite board is widely used in the field of Geothermal Engineering, highway, airport runway, square ground, large refrigerator and car decorative heat preservation etc..

　　3、稳定性、防腐性好

　　3, stability, good corrosion resistance

　　长时间的使用中，不老化、不分解、不产生有害物质，其化学性能极其稳定，不会因吸水和腐蚀等导致降解，使其性能下降，石墨挤塑板在高温环境下仍能保持其优越的性能，根据有关资料介绍，XPS挤塑保温板即使使用30～40年，仍能保持优异的性能，且不会发生分解或霉变，没有有毒物质的挥发。

　　The use of the long time, aging, decomposition, does not produce harmful substances, the chemical property is very stable, not as a result of corrosion due to water absorption and degradation, the performance drop, graphite extruded plate can still keep its excellent performance in high temperature environment, according to the information, even when using the 30 XPS extrusion molding insulation board to 40 years, can still maintain excellent performance, and does not decompose or mildew, no toxic substances volatile.
