High-Performance Thermal Insulation for Air Duct & Pipeline Systems

THERMAL INSULATION FOAM (also known as Chemically Cross-Linked Polyethylene Foam, or XPE) is a closed-cell cross-linked polymer foam engineered specifically for HVAC air duct and pipeline thermal insulation applications.

Manufactured using low-density polyethylene (LDPE), AC foaming agents, and eco-friendly functional additives, the raw materials are melted, mixed, extruded, chemically cross-linked, and continuously foamed under high temperature. This process creates a lightweight, flexible closed-cell substrate with excellent thermal performance and long-term durability.

For HVAC applications, the foam can be laminated with reflective aluminum PET foil and pre-coated with a water-based self-adhesive backing, forming an integrated duct insulation wrap that simplifies installation and enhances energy efficiency.

Whether you're insulating commercial buildings, industrial ventilation systems, or refrigeration equipment, XPE foam delivers cost-effective, multi-functional performance that engineers and contractors trust.

XPE foam is manufactured using chemical cross-linking technology – a process where cross-linking agents are evenly blended into polyethylene pellets during extrusion. After high-temperature foaming, a stable three-dimensional polymer network forms inside the foam, creating independent closed cells that trap air and resist heat transfer.

Because the cross-linking is achieved chemically (rather than through electron beam radiation), we can maintain stable mass production quality and offer shorter delivery cycles for large engineering orders – without compromising thermal performance.

XPE Thermal Insulation Foam is widely used in:

• Central Air Conditioning Systems – Insulation for rectangular and round air ducts

• Commercial Buildings – Offices, shopping malls, hotels, hospitals, schools, and exhibition centers

• Industrial Ventilation – Factory workshop ventilation and exhaust pipelines

• Refrigeration Equipment – Anti-condensation insulation for cold storage and air handling units

• Low-Temperature Pipelines – Heat preservation and insulation for chilled water and refrigerant lines

• Shock Absorption & Buffer – Vibration damping and impact protection for mechanical systems

1. Balanced Thermal Performance – The independent closed-cell structure delivers consistent insulation with a competitive price point, ideal for budget-conscious engineering projects.

2. Fire Safety You Can Rely On – Classified as full fire resistance material, flame spread is stopped within 60 seconds – giving you peace of mind and regulatory compliance.

3. Ready-to-Install Design – The aluminum PET foil facing reflects heat, while the self-adhesive backing eliminates the need for glue or clips. Just peel, stick, and seal.

4. Proven in the Field – Used in thousands of commercial and industrial projects worldwide – from shopping malls and hospitals to factories and cold storage facilities.

5. Customizable – Available in multiple thicknesses, lengths, and packaging options to meet your specific project requirements.
