挤塑保温板具有完美的闭孔蜂窝结构，这种结构让挤塑保温板在吸水率、导热系数以及蒸气渗透系数等方面均低于其他类型板状保温材料，因此具有高抗压、轻质、不透气、耐腐蚀、不降解等特点。挤塑板的导热系数小于等于0.028w/mk，远远低于其他的保温材料，因此具有高热阻、低线性膨胀率的特点。普遍适于屋面保温隔热系统、冷冻库、墙体内外的保温隔热，效果无与伦比。

Extruded insulation board has a closed cell cellular structure perfect, this structure allows aspects of extruded insulation board in water absorption, thermal conductivity and vapor permeability coefficient were lower than other types of heat insulation materials, so it has high compressive strength, lightweight, breathable, corrosion and degradation etc.. The thermal conductivity of the extruded plate is less than or equal to 0.028w/mk, which is much lower than that of other insulation materials. Therefore, it has the characteristics of high thermal resistance and low linear expansion rate. Generally suitable for roofing insulation system, freezer, wall insulation inside and outside, the effect is unmatched.
