Wanbo PIR energy saving insulation Air Duct (panel) is technical renewal promotion of "Wanbo Fast-loading Aluminum Composite Heat-preserving Air Duct (panel)”and "Wanbo PIR energy   saving insulation Air Duct (panel)”. It has the outstanding fire protection perforamce and the heat performace, and its thermal conductivity reaches 0. 018w/mk lowly (25 centidegree)which is the best heat insulation performance in the global until now and the most obvious energy construction effect's air conditioning duct(panel)

PIR is the best products which ShangHai WanGuo Technology Development Co., Ltd. after years of research  and development and through ten thousand times tests to succeed implants the polyurthen chain in the isocyanogen area diethylene glycol dinitrate member chain to obtain one kind of new high polymer synagma-Polyisocyanurate which both gathers the isocyanogen urea diethylene glycol dinitrate outstanding fire protection performance and polyurthen outstanding heat insulation performance . Polyisocyanurate broke the polyurthen foam plastics fire-limit and has broade application of space and development prospects in the military, aerospace, architecture and other fields.
