4. Key Benefits Of Aluminum Film

• Enhanced Thermal Performance: The aluminum foil reflects over 95% of infrared radiation, significantly reducing heat transfer.

• Moisture and Vapor Barrier: Prevents water vapor penetration, protecting aerogel from moisture absorption and performance degradation.

• Improved Durability & Weather Resistance: Resists UV, chemical corrosion, and salt spray for longer service life in harsh environments.

• Surface Strength & Safety: Smooth, durable surface reduces dust release during installation and handling.

• Superior Fire Resistance: Aluminum is non-combustible, providing an extra layer of fire protection.

5. Applications

• Building Exterior Insulation

Ideal for high-temperature, high-humidity, and energy-saving wall systems.

• Industrial Pipeline Insulation

Suitable for oil, chemical, and gas pipelines, reducing heat loss and providing safety protection.

• Energy Storage Systems

Used in battery cabinets and compartments to prevent thermal runaway and block external heat sources.

• Cold Chain Transportation

Applied in refrigerated truck doors and walls to minimize cooling loss and prevent condensation.

• Marine & Offshore Equipment

Protects against moisture, corrosion, and heat in marine environments.

6. Performance Characteristics

• High compactness:

Lightweight material that withstands high pressure; suitable for transportation, installation, and matching various load-bearing conditions.

• Excellent thermal insulation:

Same insulation performance at reduced thickness compared to traditional insulation, offering more space and efficient utilization.

• Flame resistance: Excellent fire resistance.
• Good adhesion:

Strong bonding with various substrates; stable even under moisture and temperature fluctuations.

• Non-combustible & Safe:

No harmful emissions when exposed to open flame or high temperatures, with high safety and reliability.

• Non-toxic: Harmless to humans and the environment.
