Neoprene flexible duct connectors are a popular choice for flexible duct connector fabric due to its exceptional durability and resistance to various environmental factors. It offers excellent resistance to heat, ozone, oils, and chemicals, making it suitable for demanding HVAC applications. Neoprene flexible duct connectors provide a reliable and long-lasting solution, ensuring optimal performance in harsh conditions. Neoprene is recommended for use in application where high mechanical strength is required. They are extremely resistant to most alkalies, gasoline and toxic fumes. Rated Class 1 as per BS 476, part 7 Flame Tests.
Vinyl flexible duct connectors are known for their flexibility and affordability. This material is lightweight, easy to handle, and highly flexible, allowing for easy installation in tight spaces. While not as durable as some other materials, vinyl connectors offer cost-effective solutions for less demanding HVAC applications. Vinyl is the most commonly used flexible duct connector fabric for all air duct installations due to its high tear strength and high abrasion resistance. Recommended for low to medium pressure ductwork systems.
Silicone flexible duct connectors are widely recognised for their outstanding flexibility, high-temperature resistance, and excellent electrical insulation properties. They can withstand extreme temperature ranges, making them suitable for applications where heat resistance is crucial. Silicone connectors also exhibit good resistance to chemicals and UV radiation, ensuring longevity in diverse environments.
Hypalon flexible duct connectors are a synthetic rubber material renowned for its exceptional resistance to ozone, heat, chemicals, and weathering. Flexible duct connectors made from hypalon exhibit excellent durability and can withstand demanding conditions, including exposure to UV radiation and extreme temperatures. This flexible duct connector fabric is ideal for applications that require superior resistance to environmental factors. Recommended for roofing, rooftop applications.
Polyurethane flexible duct connectors strike a balance between flexibility and durability. While they may be fragile in construction, they offer extended resistance to high temperatures, making them ideal for HVAC applications where thermal resistance is crucial. Despite their fragility in construction, proper installation and maintenance can mitigate concerns. Polyurethane connectors excel in high-temperature environments, ensuring reliable performance over time.
Canvas flexible duct connectors are a traditional option that offers flexibility and cost-effectiveness. While not as common as other flexible duct connector fabrics, canvas connectors can still provide a reliable connection in less demanding HVAC applications. They are lightweight, easy to handle, and offer moderate resistance to heat and wear for applications indoors and outdoors.
Conclusion:
Flexible duct connector fabrics come in various materials, each with its own unique characteristics and benefits. Whether you prioritize durability, flexibility, heat resistance, or cost-effectiveness, there is a material that suits your specific HVAC needs. From the exceptional durability of neoprene to the flexibility of vinyl and silicone, and the resistance of hypalon, polyurethane, and canvas, selecting the right material ensures optimal performance and longevity of your flexible duct connectors. Consider the environmental conditions and application requirements to make an informed choice, ultimately enhancing the efficiency and reliability of your HVAC system.
