Product Definition: The core positioning of the New Composite Air Duct
are composite air duct products based on phenolic foam insulation materials. They take phenolic foam as the core insulation layer and are covered with high-strength protective surface layers (such as color steel plates, aluminum foil, glass fiber cloth, etc.) through special composite processes.
They are mainly used for air transportation in building ventilation and air conditioning systems, replacing traditional galvanized steel plate air ducts, fiberglass reinforced plastic air ducts, etc. It has multiple functions such as heat preservation, structural support and fire prevention.
Core Structure: Three-layer composite performance guarantee
Core layer:
Phenolic foam board, with a thermal conductivity of ≤0.025W/(m · K) (at 25℃), a closed-cell rate of over 95%, featuring both thermal insulation and a certain structural strength.
Inner layer and Outer layer:
Inner layer: Mostly made of aluminum foil or fiberglass cloth, it is smooth, flat and has strong air tightness, reducing the resistance of air transportation and preventing condensation on the inner wall of the air duct at the same time.
Outer layer: Select color steel plate (for indoor dry environment) or galvanized aluminum-magnesium plate (for humid/outdoor environment) according to the scene. It is impact-resistant and corrosion-resistant, ensuring the overall structural stability of the air duct.
