Delta Duct XLPE Tube

Delta Duct XLPE Tube is a high-performance, closed-cell cross-linked polyolefin foam insulation designed for superior thermal, acoustic, and condensation control in HVAC and piping systems. Manufactured by Delta Duct Air Conditioning L.L.C., UAE, this insulation ensures long-lasting energy efficiency and durability across commercial, industrial, and residential environments.

Construction & Design

The Delta Duct XLPE Tube is made from chemically cross-linked polyethylene (XLPE) foam using advanced extrusion technology. The cross-linking process enhances mechanical strength, thermal stability, and chemical resistance while maintaining flexibility for easy installation.

• Material: Cross-linked closed-cell polyolefin foam
• Structure: Uniform closed-cell construction minimizing heat transfer and moisture ingress
• Surface Finish: Smooth external surface for aesthetic appeal and easy cleaning
• Available Forms: Tube sections for various pipe diameters and insulation thicknesses

This engineered design ensures exceptional insulation performance for chilled water, refrigeration, and ductwork systems while reducing energy loss and preventing condensation.

Key Features

• Excellent Thermal Insulation: Low thermal conductivity (0.033 W/m·K at 23°C) reduces energy loss.
• Closed-Cell Structure: Provides complete resistance to water vapor absorption and moisture penetration.
• Energy Efficient: Enhances HVAC performance and lowers operating costs.
• Fire Safety Rated: Classified as Class O per BS 476 Part 6 & 7 and compliant with ASTM E84.
• Wide Operating Range: Performs efficiently between -80°C to +105°C.
• Environmentally Friendly: CFC- and HCFC-free with low VOC emissions.
• Long Service Life: Resistant to corrosion, mold, and microbial growth.
• Easy Installation: Lightweight, flexible, and easy to cut and fit around pipes.
