挤塑保温板特点
Characteristics of extruded insulation board
XPS板具有完美的闭孔蜂窝结构，这种结构让XPS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。XPS板在欧美国家是极为普通的保温热材料，特别适用于采用倒置式屋面保温隔热工艺(up-setdown)的屋面保温隔热系统、冷动库、墙体内外的保温隔热、家庭装潢等方面。该产品适用于屋面隔热层无论隔热效果、施工简便性、总造价、使用寿命等都比传统的珍珠岩更具有优势，为新型环保节能材料，是目前建筑装饰行业的首选材料。
XPS boards have perfect closed-cell honeycomb structure. This structure makes XPS boards lower than other types of plate insulation materials in water absorption, thermal conductivity and vapor permeability. Therefore, XPS boards have the characteristics of high pressure resistance, light weight, impermeability, corrosion resistance and non-degradation. XPS board is a very common thermal insulation material in European and American countries, especially suitable for the use of upside-down roofing insulation system, cold storage, wall insulation inside and outside, home decoration and so on. This product is suitable for roofing insulation layer regardless of heat insulation effect, construction simplicity, total cost, service life and other advantages than the traditional perlite, for new environmental protection and energy-saving materials, is currently the preferred building decoration industry materials.
XPS/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
The thermal conductivity of XPS / extruded sheet is less than or equal to 0.028w/mk, which is much lower than other thermal insulation materials, so it has the characteristics of high thermal resistance and low linear expansion rate. It is universally suitable for roof insulation system, freezer, wall inside and outside insulation, the effect is unparalleled
