The primary construction material used for manufacturing ductwork is grey block copolymer polypropylene.
For external ventilation, UV-stabilized polypropylene in blue is used because the additives mixed into the material protect it from ultraviolet radiation from sunlight.
Additionally, grey polypropylene with flame-retardant additives can be used, allowing ducts to be used in environments with high fire safety requirements as the flame retardants significantly reduce the flammability of polypropylene.
Polypropylene is utilized across a wide operating temperature range from -20°C to +80°C.
Ducts made from polypropylene offer several advantages including:

- Katie:Why is a Plastic Duct so good?Support:Plastic ducts offer several compelling advantages that make them an excellent choice for various applications, especially in HVAC systems and industries requiring clean or controlled environments. Here's why plastic ducts are so good:
- Corrosion Resistance: Plastic ducts are highly resistant to corrosion, which makes them suitable for environments where moisture, chemicals, and other corrosive substances are present. This characteristic extends the lifespan of the ductwork significantly compared to traditional metal ducts.
- Chemical Stability: They can withstand exposure to a wide range of chemicals without degrading, making them ideal for use in chemical plants, laboratories, and other industrial settings.
- Lightweight: Plastic ducts are much lighter than metal ducts, which simplifies the installation process. This weight reduction can lead to lower shipping and handling costs, as well as easier maneuverability during installation.
- Low Maintenance: They require less maintenance because they do not rust or corrode. Additionally, the smooth interior surfaces of plastic ducts minimize the buildup of dust and other particulates, which can enhance air quality and reduce the frequency of cleaning.
- Energy Efficiency: Plastic ducts often have better insulation properties than metal, helping to maintain temperature control more efficiently. This can lead to energy savings by reducing the heating and cooling demands on HVAC systems.
- Versatility: They can be manufactured in various sizes and shapes, and custom configurations can be easily made to fit specific installation requirements. This adaptability makes them suitable for both new construction and retrofit projects.
- Cost-Effectiveness: While the initial cost might be higher in some cases, the long-term savings due to reduced maintenance, energy efficiency, and longer lifespan often make plastic ducts a more cost-effective option over time.
- Safety and Comfort: Plastic ducts do not conduct heat as metal does, reducing heat loss and avoiding the risk of burns from touching hot ductwork. They also tend to operate more quietly, reducing noise in the duct system.
- Corrosion Resistance: Plastic ducts are highly resistant to corrosion, which makes them suitable for environments where moisture, chemicals, and other corrosive substances are present. This characteristic extends the lifespan of the ductwork significantly compared to traditional metal ducts.
- Katie:In which industries are Plastic Duct used?Support:Plastic ducts are utilized across a broad range of industries due to their versatility, durability, and resistance to corrosion and chemicals. Here are some of the key industries where plastic ducts are extensively used:
- HVAC Systems: In residential, commercial, and industrial buildings, plastic ducts are commonly used in heating, ventilation, and air conditioning systems to distribute air efficiently and maintain indoor air quality.
- Chemical Industry: Plastic ducts are ideal for the chemical industry because they resist corrosion from harsh chemicals and vapors. They are used in chemical plants for venting and exhaust systems to safely manage emissions.
- Laboratories and Clean Rooms: Due to their non-reactive nature, plastic ducts are used in laboratories and clean rooms where contamination must be minimized. They help maintain strict air quality standards required for scientific research and semiconductor manufacturing.
- Food and Beverage Processing: Plastic ducts are used in the food and beverage industry because they do not rust or corrode, which helps prevent contamination of food products. They are also easy to clean, supporting stringent hygiene standards.
- Medical and Pharmaceutical Facilities: Similar to laboratories, these industries require environments free of contaminants. Plastic ducts contribute to creating and maintaining sterile conditions necessary for medical and pharmaceutical applications.
- Waste Water Treatment Plants: The resistance of plastic ducts to moisture and various chemicals makes them suitable for wastewater treatment plants where they can be used for air management without the risk of corrosion.
- Marine Applications: The corrosion-resistant properties of plastic ducts make them suitable for use in marine environments, where saltwater and high humidity can quickly degrade more traditional materials like metal.
- Mining and Metal Processing: These industries often involve corrosive gases and extreme environments where plastic ducts can provide reliable and durable solutions for air handling and ventilation.
- Agriculture: In greenhouses and farms, plastic ducts are used for ventilation and air distribution, helping to control temperature and humidity levels efficiently.
- HVAC Systems: In residential, commercial, and industrial buildings, plastic ducts are commonly used in heating, ventilation, and air conditioning systems to distribute air efficiently and maintain indoor air quality.
