Product Description
Nano-Aerogel Blanket Silica Thermal Insulation Fireproofing Cotton
Aerogel felt is a flexible thermal insulation material featuring aerogel as its core component, typically reinforced with a substrate of glass fiber or pre-oxidized fiber felt.
Technical Specifications
| Parameter | Typical Range | Remarks |
|---|---|---|
| Thermal Conductivity | ≤0.020 W/(m*K) (25℃), some reaching 0.012-0.018 | Lower value means better insulation effect and thinner required thickness |
| Density | 180-220 kg/m³ | Much lower than traditional insulation materials, favorable for lightweight design |
| Service Temperature | Standard: -50℃ ~ 200℃; High-temp grade: -50℃ ~ 600℃ or higher | Selected by model; covers most rail transit scenarios |
| Fire Rating | Class A non-combustible; high-end rail transit products meet EN 45545-2 HL3 | HL3 is the highest hazard level, indicating compliant smoke density, toxicity and heat release |
| Water Repellency Rate | ≥98% | Overall hydrophobic, no collapse when wet, stable insulation performance |
| Thickness | 3/5/6/10 mm (common) | Customizable; much thinner than traditional insulation materials |
| Width | 1500 mm (standard) | Cuttable; adapts to complex-shaped surfaces |
Key Features & Benefits
- High Thermal Efficiency: Features extremely low thermal conductivity, achieving the insulation performance of thick traditional materials with only a thin layer.
- Fire Safety: Class A non-combustible; does not drip at high temperatures, produces low smoke and no toxic fumes, and meets EN 45545-2 HL3 requirements.
- Noise and Vibration Reduction: Porous structure absorbs sound and dampens vibration, enhancing passenger comfort.
- Lightweight: Extremely low density significantly reduces vehicle weight and lowers operational energy consumption.
- Space-Saving: Thickness is far less than that of traditional insulation materials, freeing up valuable space for cabin design.
- Superior Comprehensive Performance: A single material simultaneously addresses thermal insulation, fire safety, and noise reduction.
