聚氨酯保温芯材的主要原料之一是聚氨酯硬泡组合聚醚，又称白料，与聚合MDI共称黑白料。聚氨酯泡沫保温板的保温隔热原理是依靠闭孔发泡隔离空气为微小气泡单元，通过降低空气流动实现隔热保温效果，是目前所有保温材料中导热系数最低的。硬质聚氨酯泡沫板导热系数低，热工性能出色，当容重为38~42kg/m2，导热系数仅为0.018-0.023w/m.k。硬质聚氨酯的闭孔率在95%以上，属于憎水性材料，不会因吸潮增大导热系数，墙面也不易渗水。聚氨酯在添加阻燃剂后是一种阻燃材料，燃烧时表面会形成碳化层，有助隔离下层泡沫，有效防止火灾蔓延，并且在高温中不产生有害气体。聚氨酯材料孔隙是闭孔结构，结构稳定，抗变形、抗冻融、不易开裂、隔音吸声，使用寿命长达30年以上

One of the main raw materials of PU insulation core material is PU rigid foam combined withpolyether, also known as white material, and together with polymeric MDI, they are collectivelyknown as black and white materials. How the PU foam insulation panel insulates heat relies onclosed-cell foaming, which isolates air into tiny bubble units, and achieves thermal insulationeffect by reducing airflow. Currently, it is the material with the lowest thermal conductivity amongall thermal insulation materials. Rigid PU foam panel possesses low thermal conductivity andexcellent thermal performance. When the density is 38-42kg/m3, the thermal conductivity standsonly at 0.018-0.023w/m-k. The closed cell rate of rigid PU is above 95%, making it a hydrophobicmaterial. It will not increase the thermal conductivity due to moisture absorption, and the wall willnot easily seep water. PU is a flame-retardant material after adding flame retardant. When burning,a carbonized layer is formed on the surface, which helps isolate the underlying foam, effectivelyprevents the spread of fire, and produces no harmful gases at high temperatures. The pores of thePU material features a closed-cell structure, which is stable in structure, resistant to deformation,freezing and thawing, and not easy to crack, while insulating and absorbing sound, with a servicelife of over 30 years.

Berbson has teamed up with the international chemical giant BASF to jointly develop a newgeneration of PIR sandwich insulation panel, which adopts the internationally advanced six-component online foaming technology. The dense foam is fully bonded with the surface materialto form an uninterrupted heat shield, effectively blocking heat conduction with an excellent thermalinsulation performance. Applicable to working temperatures of - 170°C-+100°C, the advancedfluorine-free pentane foaming process is able to better protect the ozone layer of our planet fromdamage.
