XLPE
XLPE (Cross-linked Polyethylene) Foam Insulation
XLPE (Cross-linked Polyethylene) Foam is a high-performance, closed-cell, lightweight insulation material created through a chemical or physical cross-linking process. This unique structure provides an excellent thermal barrier, superior moisture resistance, and outstanding flexibility, making it the ideal choice for insulating HVAC systems, chiller pipelines, and cold-storage units. We specialize in providing a full range of non-fibrous XLPE products, including Class O rated variants for fire-safety critical applications.

Detailed Information
Key features
XLPE foam’s closed-cell structure delivers essential performance benefits that contribute to energy efficiency and long-term system integrity.
- Excellent Water & Vapor Barrier:
The closed-cell structure acts as an internal vapor barrier, preventing condensation (sweating) and eliminating the need for an external vapor retarder.
- Low Thermal Conductivity:
Ensures a very low heat transfer rate, maximizing thermal efficiency and reducing operational energy costs for cooling and heating.
- Class O Fire Rating:
Many variants are formulated to meet the Class O fire standard, offering high fire resistance and low smoke emission for enhanced safety.
- Flexibility & Ease of Installation:
Highly flexible and lightweight, making it easy to cut, shape, and install on complex shapes and tight areas, minimizing installation time and waste.
- Durable & Chemical Resistant:
Resists chemicals, fungal growth, and abrasion, ensuring a long service life and low maintenance.
- Non-Fibrous & Non-Porous:
Ideal for applications where fiber shedding is a concern, such as clean rooms, hospitals, and food processing plants.
Applications
XLPE insulation is widely used in commercial, residential, and industrial construction, particularly in low-temperature and HVAC systems.
- HVAC Duct Insulation:
Used externally on supply and return air ducts to prevent thermal loss and condensation.
- Chilled Water and Refrigeration Piping:
Essential for insulating cold lines to maintain temperature and prevent pipe sweating.
- Cold Storage & Refrigeration Units:
Lining walls, ceilings, and floors in temperature-controlled warehouses and cold rooms.
- Clean Room Environments:
Chosen for its non-fibrous nature and fire safety compliance in pharmaceutical, microchip, and electronic manufacturing facilities.
- Acoustic Damping:
Can be used under screeds or within partitions for impact sound and vibration reduction.
Facing Options
The performance of XLPE is often enhanced with protective and functional facings.
- Plain (Unfaced):
Used when the foam is enclosed, or for acoustic damping applications.
- Aluminum Foil (Alu Foil):
Provides a robust, reflective external vapor barrier and a neat finish.
- Aluminum Polyester (ALUPET):
A strong, multi-layered film offering superior vapor resistance and high aesthetic value.
- Glass Cloth (GC):
Offers excellent protection against mechanical damage and improved resistance to UV exposure.
- Self-Adhesive Backing:
Available for sheets and pipe sections to facilitate quick and secure installation.
Temperature Range
XLPE is primarily utilized in cryogenic and medium-temperature applications where its flexibility and closed-cell properties are vital
- Operating Temperature:
Typically suitable for continuous service from -40°C to +115°C (or higher depending on specific formulation).
- Cold Application Integrity:
Maintains superior thermal and mechanical properties down to cryogenic temperatures.
Size, Density & Thickness
We provide customizable dimensions to suit the exact requirements of any project specification.
- Density:
Available in densities typically ranging from 25 kg/m³ to 33 kg/m³, offering a balance of flexibility and structural integrity.
- Thickness (Sheets/Rolls):
Common thicknesses range from 6 mm up to 50 mm, supplied in rolls or sheets.
- Thickness (Pipe Sections):
Available in standard industry thicknesses (e.g., 9mm, 13mm, 19mm, 25mm) to match specific pipe sizes and insulation requirements.
