Phenolic Aluminum Duct

Composite Layer Design: Each layer works synergistically to form a stable and high-efficiency ventilation system, with the specific composition as follows:

Inner & Outer Protective Layers: Adopt 60/80-micron embossed aluminum foil coated with a high-temperature resistant epoxy primer. This not only enhances the structural strength of the air duct but also effectively resists ultraviolet (UV) erosion and moisture penetration, making it suitable for various indoor and outdoor installation environments. The smooth inner wall of the aluminum foil reduces air flow resistance and wind loss, while preventing fiber shedding and microbial growth to ensure air supply hygiene.

Core Insulation Layer: Made of closed-cell rigid foam with modified phenolic resin as the base material, produced via a fluorine-free foaming process. The density is controlled between 45-60kg/m³. As the core of the air duct's energy-saving performance, its high closed-cell rate results in a thermal conductivity as low as 0.02W/(m·K), which is far superior to traditional insulation materials. It also possesses excellent sound insulation and fire resistance properties.

The specialized composite process endows the air duct with exceptional dimensional stability, featuring a compressive strength of 0.25MPa. It can maintain structural integrity within a maximum operating temperature of 80℃ without shrinkage or embrittlement.

Core Advantages of Phenolic Aluminum Duct

Compared with traditional air ducts, phenolic aluminum foil composite air ducts achieve comprehensive breakthroughs in energy efficiency, safety, installation, and other dimensions. Key performance advantages are as follows:

1. Ultimate Energy Efficiency: System Energy Consumption Reduced by 30%+

The phenolic foam core material has a thermal resistance of 33-36 (m·℃)/W, with thermal insulation performance far exceeding that of traditional iron sheet air ducts. It can significantly reduce cold and heat loss during air conditioning operation. Combined with professional sealing treatment (air leakage rate ＜1%), the system energy consumption is reduced by more than 30%, resulting in substantial electricity cost savings during long-term use.

2. Safe and Reliable: Class B1 Fire Rating + Low-Toxicity Guarantee

Certified by authoritative institutions with a Class B1 fire rating, it carbonizes without spreading when exposed to fire, self-extinguishes after being away from fire, produces no dripping during combustion, and releases non-toxic gases, with a fire resistance limit of 2 hours. Note: Not suitable for smoke control and exhaust systems; Class A non-combustible materials shall be selected for such scenarios.

3. Lightweight and Efficient: Installation Efficiency Increased by 3-5 Times

With a weight only 1/8 of traditional iron sheet air ducts (1.4-2kg/㎡), it reduces building load-bearing. No large machinery is required; on-site cutting and splicing are convenient, increasing installation efficiency by 3-5 times and reducing labor costs by more than 50%. Its flexible structure can minimize construction conflicts.

4. Hygienic and Durable: Suitable for High-Cleanliness Scenarios

The smooth aluminum foil inner wall is not prone to dust accumulation, and no fiber shedding occurs when the wind speed is ≤20m/s, meeting the cleanliness requirements of hospitals, food factories, and other venues. The composite structure is resistant to weak acids and alkalis, with a service life of over 15 years in humid environments-50% longer than traditional air ducts.

5. Noise-Reducing and Environmentally Friendly: Creating Comfortable Environments

The porous structure of phenolic foam enables sound absorption and noise reduction (noise reduction capacity: 3-19dB/m), reducing noise by 5-10 decibels compared with traditional air ducts. Additional silencers are not required in most scenarios. Produced with fluorine-free foaming agents, it is recyclable after disposal, complying with environmental protection standards.
