                硬泡聚氨酯復①合板

                硬泡聚笑著搖了搖頭氨酯復合板

                硬泡聚氨酯復合板,又稱PU復合板,是以熱固性我怎麽感覺他材料硬泡聚氨酯為芯材,在工廠制成●的、雙面帶有界面層的保溫板。

                導熱系數:0.024
                燃燒性能等級:B1/B2,
                熱固性材料
                導熱⊙系數低,可有效降低保溫板材的設計厚度
                對基層平整度要求較高
                材料價格較高
