1. HVAC & Duct Sealing
Linerless aluminum foil tape is widely used for sealing air ducts, insulation layers, and ventilation pipelines.
The tape provides an excellent air-tight seal, preventing leakage, improving system efficiency, and enhancing thermal performance.
Its high-temperature resistance and strong adhesion make it suitable for long-term use in heating, cooling, and ventilation systems.

2. High-Temperature Pipe Insulation
Thanks to its aluminum foil’s heat-resistant properties, this tape is ideal for wrapping steam pipes, hot water lines, and industrial insulation materials.
It helps reduce energy loss, stabilizes temperatures, and provides a protective layer that resists heat, moisture, and corrosion.

3. Refrigeration & Cooling Systems
The tape is commonly used in refrigerators, freezers, air conditioners, and cooling units.
It is applied for:
Copper tube binding
Fixing insulation foam
Reducing condensation
Enhancing cooling efficiency
Its linerless design enables quick application on assembly lines, making it popular in home appliance manufacturing.

4. Industrial Assembly & Metal Surface Repair
The tape bonds well to metals and composite materials, making it ideal for:

Temporary sealing
Metal surface patching
Reinforcing insulation materials
General industrial maintenance
Its durability and moisture barrier offer reliable performance even in harsh environments.

5. Construction & Building Protection
In building applications, the tape is used for:
Sealing reflective insulation panels
Preventing moisture penetration
Enhancing thermal insulation layers
Repairing roofs, gutters, and metal structures
Its weather resistance provides longevity for indoor and outdoor use.

1. Linerless Design for Faster Work
No release paper means faster installation, especially for contractors and assembly-line operations.

2. High Temperature Resistance
Suitable for hot air ducts, steam pipes, insulation materials, and areas exposed to heat.

3. Excellent Moisture & Vapor Barrier
Prevents air leakage, condensation, and corrosion.

4. Strong Adhesion
Provides secure bonding on metal surfaces, insulation materials, and composite structures.

5. EMI/RFI Shielding
The aluminum layer blocks electromagnetic interference, ideal for cable wrapping and electronics.
