Phenolic foam ducting panel is of high strength, taking the phenolic foam as the core material and with aluminum foil on both sides. It is non-combustible material, which has no smoke and innocuity while catching fire and the bending strength reaches over 1MPa and the thermal conductivity index reaches 0.025W/mK. The phenolic foam can be fabricated into all kinds of rectangular (bended) ducts by cutting and adhesive connecting, and can be fabricated into the air ducts of all kinds of specifications and shapes by using the combustion resistant flange and adhesive. It is widely used for the air conveyance systems of central air conditioning units in hotels, apartments, hospitals, office buildings and other deluxe high-rise buildings.

HUAHAI Phenolic foam air ducts for central air-conditioning has six advantages compared with the traditional air duct products on the market. The advantages are as follows:

1. Low thermal conductivity (0.025w/ m.k) ensures excellent insulation property.
2. Light weight for transportation and handling (1.4kg/ m2) duct work eliminates having to use heavy duty anchors and supports.
3. Long service life.
4. Temperature capabilities ( -150 °C to 150°C)
5. Easy to install which helps on cost savings.
6. Uniform in appearance of the installed duct work.
