Haohai Phenolic pre-insulated duct is another successful development after polyurethane pre-insulated duct was developed. Supported by a famous university and some overseas technology. Haohai R&D team used new phenolic process to make the duct has a high performance. The same goes to the polyurethane duct, it is also a modern heat insulate material. The core of the duct is phenolic foam, with surfaces both aluminum foils(Mode HPFA) or one side aluminum foil, the other side steel(Mode HPFAS). Phenolic is a high performance material in fireproofing, heat insulation, soundproofing, and energy saving. The working temperature range is from -50℃ to 150℃.
Compared to other material ducts, Haohai phenolic pre-insulated duct’s advantage is the excellent fireproof characteristics. All the specifications meet the A class fire retardancy of the National Standard. Haohai phenolic pre-insulated duct is made by continuous pressure process line, so it has a stable quality and high cost performance. That can easily meet the demands of lower price required by some projects.
