Good news from Haohai Research Center: The research project of “B1 flame-retardant PU preinsulated duct panel” that our company had declared has got Innovation Foundation from Shanghai Science Committee.

Haohai group is a high-tech enterprise. Powerful technology, perfect testing condition, advanced producing equipment, transferring scientific research fruit into productivity, which brings our company to the market. The project is a new trend of international duct material’s development. It is high technology, high productivity and specific market. Adding a new species to our country’s duct industy as the successful exploitation.

The traditional duct is composed by zincification armor plate and glass fibre。 Main disadvantages are as follows: Bad rot proof performance, bad heatproof performance, cumbersome and short life-span B1 heatproof PU pre-insulated panel is a newcomer of duct materials. It has many advantages such as excellent heat insulation, lightweight, low air leakage, healthful, high construction efficiency, long life-span. It adopts environment protective foam.
