PUR Duct Aluminium Panels

1. Polyurethane foam insulation layer: Polyurethane foam has a closed-cell structure, with a closed-cell rate typically reaching around 98%. It can effectively prevent air convection and reduce heat transfer. Its thermal conductivity is low, generally between 0.02 and 0.023W/(m · k), providing excellent thermal insulation and heat preservation effects.

2. Aluminum foil layer: Aluminum foil with a thickness of 60 microns or 80 microns or 150-180 micron Aluminum Sheet has excellent moisture-proof and vapor-barrier properties, effectively preventing water vapor in the air from entering the insulation layer and avoiding the reduction of insulation performance of the insulation material due to moisture.

1. Good fire resistance:

The core material of some polyurethane foam insulation board air ducts can reach the B1 standard of flame retardancy. When burning, it can form a carbonized layer to prevent the spread of flames, and the smoke emission is low, meeting relevant fire protection requirements.

2. Corrosion-resistant and antibacterial:

The surface of aluminum foil is smooth, making it less prone to bacterial and mold growth, and it also has certain corrosion resistance. This can effectively ensure the quality of the air delivered by the air conditioning system and prevent pollution to the indoor environment.

3. Good thermal insulation performance:

The combination of low thermal conductivity polyurethane foam and reflective aluminum foil can significantly reduce the cold and heat loss of the air conditioning system, improve energy utilization efficiency, and achieve energy conservation and consumption reduction.

HVAC (Heating, Ventilation and Air Conditioning) systems: Central ventilation/air conditioning ducts for residential buildings, commercial office buildings and hotels, relying on the thermal insulation and heat preservation properties of PUR core materials, reduce cold and heat loss. Meanwhile, the aluminum foil layer is moisture-proof and easy to clean, meeting the indoor air circulation requirements.

Ventilation and temperature control in industrial plants: Ventilation and exhaust/constant temperature air ducts for electronics factories, food processing plants, and chemical workshops can withstand certain industrial environmental temperature and humidity, and their fire resistance performance (partially meeting fire protection standards) is compatible with industrial safety requirements.

Public transportation and public buildings: Centralized ventilation systems for airport terminals, high-speed railway station waiting halls, hospital outpatient buildings, and school auditoriums. The surface of the aluminum foil board is smooth and does not accumulate dust. The PUR core material has excellent sound insulation, which is suitable for the hygiene and low-noise requirements of crowded places.

Data center and computer room environment control: Precision temperature-controlled air ducts in server rooms and communication rooms. The PUR core material provides stable insulation, preventing condensation on the air ducts from affecting equipment. Meanwhile, its lightweight feature facilitates the layout of complex pipelines within the computer room.

Cleanrooms and special environments: Specialized air ducts for clean workshops in pharmaceutical factories, biological laboratories, and aseptic processing areas of food, with strong airtightness and less prone to microbial growth, meet the hygiene standards for air transportation in clean environments.
