Phenolic Foam Air Duct

Phenolic Foam Air Duct is high strength panel, which is taken the phenolic foam as the corematerial with reinforcing the aluminum foil on both sides. It is non-combustiblematerial, which has no smoke and innocuity while catching fire and the bendingstrength reaches over 1MPa and the thermal conductivity index reaches 0.020W/mK.The phenolic foam can be fabricated into all kinds of rectangular (bended) ductsby cutting and adhesive connecting, and can be fabricated into the air ductsof all kinds of specifications and shapes by using the combustion resistant flangeand adhesive. It is widely used for the air conveyance systems of central airconditioning units in hotels, apartments, hospitals, office buildings and otherdeluxe high-rise buildings Specifications: 1) Density: 50 - 60kg/m3 2) Thermal conductivity: 0.020W/mK 3) Compressing strength: 0.56MPa 4) Bending strength: 1.0Mpa 5) Combustibility property: non-combustible class "O" 6) Water absorption: 1.9% 7) Max. smoke density: 2% 8) Dimension change: 0.3% 9) Working temperature: 150°C 10) Dimensions: 3,900 x 1,200 x 20mm
