Polyurethane exhaust duct, polyurethane aluminum foil duct,air duct, polyurethane ventilation tube, polyurethane composite duct internal using cladding special glass fiber, heat isolation fiber, coating glue; External coating special glass fiber, clamp type structure in a spiral, stainless steel (VA); Widely used in various workshops, the room that defend bath, electronics factory, sewers, shipyard, refrigeration, environmental protection ventilation engineering. Drainage smoke, moisture, dust, high temperature gas, ventilated take a breath, etc.

Polyurethane exhaust duct, polyurethane aluminum foil duct, polyurethane ventilation tube, polyurethane composite duct each attribute index introduced:

1. Strength: mechanical structure stability, compression resistance to deformation.

2. Small coefficient of thermal conductivity: the determination of building research institute for 0.024 w (M.K), is better than other common thermal insulation material.

3. Fire performance is good: more than gb GB8624-97 in pipe heat insulation foam plastics combustion performance classification method of BI level requirement. In the polyurethane industry at home and abroad reached leading level.

4. No pollution: duct inside and outside for aluminum foil, its surface formation of AL2O3 has the stable chemical properties, the environment does not constitute any pollution.

5. Long service life: duct inside and outside for aluminum, the surface has the stable AL2O3, intermediate thermal insulation layer is high polymer material, service life is a traditional duct 4 to 6 times.
