Stable quality, high production efficiency now, in the case of a sharp rise in demand for polyurethane sandwich panel factory production line to produce high-quality sandwich panels density species, in addition to convenient control of the mass density of high-quality sandwich panels, the more it brings good economic and competitive; weather is good, easy to install polyurethane sandwich panels prefabricated in the factory after the density can be directly used for the construction and installation of high quality sandwich panels transaction, no additional steps, quick construction. And no need to take into account changes in the weather, according to plan production. 2, good thermal insulation properties of high quality sandwich panels use density can improve the heat resistance of the structure of building maintenance, reduce building heating and air conditioning energy consumption, energy saving. Bond strength ≥1MPa soaking water uptake 24h≤500g / M2 heat transfer coefficient 1.0W / m2.K impact strength of standard ≥3J enhanced ≥10J breathable water vapor density 1.0g / m2.h artificial weathering: 250h None cracking, chalking, flaking. The areal density of 13.0kg / m2 density of high-quality sandwich panels use | Weifang density of high-quality sandwich panels | Zhucheng Hua Yong Yong Hua Plastic Foam Plastic Foam provided by Zhucheng plant.
