Polyurethane Insulation Panel, Brand Name : HONG BAO LI

1. Polyurethane insulation panel

This polyurethane insulation panel uses chemical constituents modified blended polyether polyol, with N. P heterocyclic changing the chain structure of polyurethane. It can avoid the flame retardant losing of traditional retardant technology and second batch foaming of Polyurethane foam and make molecular structure more stable and retardant effectiveness not damping.

Polyurethane insulation panel is produced by one step pressing with rigid foam as core material and flexible inorganic membrane as surface layer of two sides in continuous production line. The product has low thermal conductivity, high flame retardant performance and good dimensional stability bonded to wall and decorative layer easily. The panel is cut by numerical control with high dimensional accuracy. This polyurethane insulation panel can meet the fireproofing rating requirements by application situation.

 1.2 Performance advantages

1.2.1 Lower thermal conductivity and lasting dimensional stability

Adopting international advanced patent technology to produce rigid foam, obtain high cell close and keep the framework of whole wall uniform and stable without shrinkage strain.

 The initial thermal conductivity is at the range of 18.5mw/（m*k）－21.5mw/（m*k）. Compared to the same building energy-saving insulation requirements for thermal insulation material, wallbody is thinner and use area of building improves 1%-3% with more saving thermal insulation material.
