1. What Are Aerogel Fiberglass and Ceramic Fiber Blankets?

Aerogel fiberglass blankets and ceramic fiber aerogel blankets are next-generation composite materials that combine ultra-low thermal conductivity with excellent flexibility. They are made by infusing silica aerogel into a base layer of E-glass fiber or ceramic fiber mat. These materials maintain the thermal insulation properties of aerogels while significantly improving mechanical strength and processability.

Aerogel fiberglass blanket: SiO₂ aerogel + E-glass fiber
Ceramic fiber aerogel blanket: SiO₂ aerogel + Al₂O₃ ceramic fiber

Both types of blankets are lightweight, flame-resistant, and suitable for demanding thermal insulation environments.

2. Ultra-low Thermal Conductivity and Flexible Wrapability

These flexible aerogel blankets combine multiple properties rarely found in traditional materials:
- Thermal conductivity as low as 0.018 W/m·K
- High-temperature resistance up to 1200°C
- UL94-5VA fire rating / GB Class A non-combustibility
- Easy to cut and wrap around complex shapes

Comparison table:

Item	Aerogel Fiberglass	Ceramic Fiber Aerogel	Rock Wool	PU Foam	Silica Blanket
Thermal Conductivity	0.018~0.023	0.020~0.028	0.035~0.045	0.020~0.035	0.030~0.050
Max Temp (°C)	850	1200	600	120	600
Fire Rating	UL94-5VA	Class A	B1	B3	B1
Flexibility	Excellent	Moderate	Poor	Moderate	Good
Weight	Light	Medium	Heavy	Light	Heavy

3. Typical Applications: From Industry to Aerospace

Flexible aerogel blankets have proven to be highly effective in a wide range of sectors:

- Industrial pipelines and valves
- Cold and hot process equipment
- Building façade insulation systems
- Aerospace insulation and cryogenic tank linings
- Battery thermal protection in EVs

Thanks to their flexible structure and form stability, these materials are ideal for high-temperature curves, irregular surfaces, and confined construction spaces.

4. Global Market Trends: A New Blue Ocean for Flexible Aerogel Mats

Driven by global sustainability goals and stricter fire safety standards, the flexible aerogel insulation market is growing rapidly. Analysts forecast a CAGR of over 15% for the next 5 years, particularly in Asia-Pacific, Europe, and the Middle East.

In North America and Europe, traditional insulation materials like mineral wool and polyurethane foam are gradually being replaced by advanced aerogel composites. Domestic Chinese manufacturers are also accelerating investments to compete with international players like Aspen Aerogels and Cabot Corporation.

5. Conclusion: Aerogel Blankets Are Redefining Thermal Management

Flexible aerogel blankets—especially those made with ceramic and fiberglass bases—are ushering in a new standard in insulation materials. They combine flame resistance, high-temperature tolerance, and low thermal conductivity in a single product line.
