XPS保温板
XPS insulation board
XPS保温板，它是以聚苯乙烯树脂为原料加上其他的原辅料与聚含物，通过加热混合同时注入催化剂，然后挤塑压出成型而制造的硬质泡沫塑料板。.它的学名为绝热用挤塑聚苯乙烯泡沫塑料（简称XPS),XPS具有完美的闭孔蜂窝结构，这种结构让XPS板有极低的吸水性（几乎不吸水）、低热导系数、高抗压性、抗老化性（正常使用几乎无老化分解现象）。
XPS insulation board, which is made of polystyrene resin and other raw materials and polymer inclusions, is heated and mixed into the catalyst at the same time, and then extruded and extruded to form rigid foam plastic plate. Its scientific name is insulation extruded polystyrene foam (XPS). XPS has a perfect closed cell honeycomb structure. This structure makes XPS board have very low water absorbency (almost no water absorption), low thermal conductivity, high compressive resistance and aging resistance (normal use almost no aging decomposition phenomenon).
聚氨酯保温板
Polyurethane insulation board
1、硬质聚氨酯板导热系数低，热工性能好。当硬质聚氨酯容重为35～40kg/m3时，导热系数仅为0.018g~0.023w/（m．k），约相当于EPS的一半，是所有保温材料中导热系数最低的一种。
1. Rigid polyurethane board has low thermal conductivity and good thermal performance. When the unit weight of rigid polyurethane is 35-40kg / m3, the thermal conductivity is only 0.018g-0.023w / (m.k), which is about half of EPS, and it is the lowest thermal conductivity of all thermal insulation materials.
2、硬质聚氨酯板具有防潮、防水性能。硬质聚氨酯的闭孔率在90%以上，属于憎水性材料，不会因吸潮增大导热系数，墙面也不会渗水。
2. Rigid polyurethane board has moisture-proof and waterproof properties. The closed cell rate of rigid polyurethane is more than 90%, which belongs to hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep.
3、硬质聚氨酯防火，阻燃，耐高温。聚氨酯在添加阻燃剂后，是一种难燃的自熄性材料，其软化点可达到250摄氏度以上，仅在较高温度时才会出现分解：另外，聚氨酯在燃烧时会在其泡沫表面形成灰，这层灰有助隔离下面的泡沫。能有效地防止火灾蔓延。而且，聚氨酯在高温下也不产生有害气体。
3. Rigid polyurethane fireproof, flame retardant, high temperature resistant. Polyurethane is a flammable self extinguishing material after adding flame retardant. Its softening point can reach above 250 degrees Celsius. It will decompose only at higher temperature. In addition, polyurethane will form ash on the surface of foam when it burns. This layer of ash helps to isolate the foam below. It can effectively prevent the spread of fire. Moreover, polyurethane does not produce harmful gas at high temperature.
4、由于聚氨酯板材具有优良的隔热性能，在达到同样保温要求下，可使减少建筑物外围护结构厚度，从而增加室内使用面积。
4. Due to the excellent thermal insulation performance of polyurethane board, the thickness of building envelope can be reduced and the indoor use area can be increased under the same thermal insulation requirements.
5、抗变形能力强，不易开裂，饰面稳定、安全。
5. Strong deformation resistance, not easy to crack, stable and safe finish.
6、聚氨酯材料孔隙率结构稳定，基本上是闭孔结构，不仅保温性能优良，而且抗冻融、吸声性也好。硬泡聚氨酯保温构造的平均寿命，在正常使用与维修的条件下，能达到30年以上。能够做到在结构的寿命期正常使用条件下，在干燥、潮湿或电化腐蚀，以及由于昆虫、真菌或藻类生长或者由于啮齿动物的破坏等外因影响，都不会受到破坏。
6. The porosity structure of polyurethane material is stable, basically closed cell structure, not only has good thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average service life of rigid polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. It can ensure that the structure will not be damaged under the normal service conditions during the service life of the structure under dry, humid or electrochemical corrosion, as well as due to the growth of insects, fungi or algae, or the destruction of rodents and other external factors.
7、综合性价比高。虽然硬质聚氨酯泡沫材的单价比其它传统保温材料的单价高，但增加的费用将会由供暖和制冷费用的大幅度减少而抵消。
7. Comprehensive cost performance is high. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by a substantial reduction in heating and refrigeration costs.
