FMA650 is a flexible high temperature aerogel insulation blanket made by NANO TECH in Shaoxing, Zhejiang, China. It combines silica aerogel with a glass fiber needled blanket and is designed for industrial pipelines, vessels, and equipment with a recommended use temperature from -50℃ to 650℃. It is also used in oil and gas plants, chemical plants, city heating systems, and buildings.
Thermal conductivity is 0.021 W/(m·K) at 25℃ and 0.036 W/(m·K) at 300℃. The blanket has a hydrophobic rate of ≥99%, volumetric water absorption of ≤1%, Class A burning level (GB 8624), bulk density of 210±20 kg/m³, and compression rebound rate of ≥90%. Standard thicknesses are 3, 5, 6, and 10mm, with 15mm and 20mm available as custom options. Width is 1500mm. Standard roll lengths are 45m (3mm), 42m (5mm), 38m (6mm), and 30m (10mm); other lengths can be customized. Colors include Beige / White as standard, with Grey / Black / Maroon on request. Facings, coatings, adhesive backing, jacketing, and private-label packaging are available for custom orders.

FMA650 Thermal Conductivity at High Temperature
The thermal conductivity of any aerogel blanket rises as temperature rises. For a high-temperature heat-loss calculation, use the conductivity at the mean insulation temperature, not the 25℃ value.
| Mean Temperature | Thermal Conductivity | Test Method |
|---|---|---|
| 25℃ | 0.021 W/(m·K) | GB/T 10295 |
| 300℃ | 0.036 W/(m·K) | GB/T 10294 |
Why Use FMA650 for High Temperature Insulation
| Benefit | What It Means for Your Project |
|---|---|
| Thin, low-conductivity insulation | 3–10mm thickness helps fit more lines into the same pipe rack and cuts heat loss in space-limited installations; thermal performance is 2–5 times better than traditional insulation products |
| Hydrophobic: ≥99% | Water repellency and ≤1% volumetric water absorption help keep moisture from collecting against the pipe, which reduces the risk of corrosion under insulation (CUI) |
| Class A burning level | GB 8624 Class A helps protect pipelines and equipment from flame |
| Flexible and easy to install | Cuts, wraps, and fits around valves, flanges, and complex surfaces |
| Physically robust | Compression rebound ≥90%, tensile strength ≥500 kPa, vibration mass loss ≤1% |
| Reusable and environmentally friendly | Contains no harmful substances and can be reused after removal, so there is less industrial waste to dispose of |
| Metal compatibility | Pass results for austenitic stainless steel, aluminum, copper, and steel covers |
FMA650 Thickness & Size Selection
| Thickness | Width | Standard Roll Length | Typical Choice |
|---|---|---|---|
| 3mm | 1500mm | 45m | Thin layer for tight clearance |
| 5mm | 1500mm | 42m | Thin single layer with extra margin |
| 6mm | 1500mm | 38m | General industrial insulation |
| 10mm | 1500mm | 30m | Thicker single layer for higher heat-loss targets |
| 15 / 20mm | 1500mm | Custom | High-temperature or high heat-loss targets where multilayer is not preferred |
The correct thickness depends on operating temperature, pipe or equipment size, target surface temperature or heat loss, ambient conditions, and available space – not on temperature alone. Where one layer is not enough, multilayer designs can be evaluated. We provide heat-loss analysis and several solutions to compare, based on your conditions.
Facings, Coatings & Custom Finishes
| Option | Purpose | What to Confirm |
|---|---|---|
| Aluminum foil facing | Moisture barrier, reflective surface, cleaner appearance | Facing temperature limit, one-side or two-side |
| Surface coating | Dust control, handling, surface protection | Coating type, service temperature |
| Adhesive backing | Faster installation on flat or large surfaces | Adhesive temperature limit, substrate |
| Jacketing / cladding wrap | Weather and mechanical protection | Outdoor exposure, mechanical load |
| Color | Identification or appearance | Grey / Black / Maroon, quantity |
| Private label / OEM branding | Your brand on rolls, labels, and packaging | Logo, packaging spec, quantity |

| Best for | Service above 450℃ | Steam, city heating, buildings up to 450℃ | LNG and cryogenic systems |
Choose FMA650 when your maximum service temperature is above 450℃. Below that, FMD450 may be the better fit.
FMA650 Installation & CUI Design Considerations
| Item | Consideration |
|---|---|
| Surface preparation | Prepare and coat the equipment surface according to your corrosion-protection specification. |
| Cutting and wrapping | Cut the blanket to your pipe or equipment dimensions and wrap it snugly; plan joints and seams in the layout. |
| External jacketing | Use cladding or jacketing suited to weather and mechanical exposure. |
| CUI management | Hydrophobic insulation helps, but CUI also depends on coatings, sealed joints, drainage, and inspection access. |
| Service above 400℃ | Layering, securing, and any intermediate layers should follow a verified installation design. Ask NANO TECH for the installation recommendation for your project before ordering. |
| Handling | As with any insulation, wear gloves, eye protection, and a dust mask when cutting in poorly ventilated areas. |

FMA650 High Temperature Aerogel Blanket FAQ
1. What is the maximum temperature of FMA650?
The recommended use temperature is -50℃ to 650℃. If your process runs near the upper limit, send the normal and maximum temperature and the operating duration so we can review your conditions.
2. Is 650℃ a continuous rating or a short-term peak?
The published specification gives one recommended use range up to 650℃ and does not separate a continuous rating from a peak rating. If your design needs that distinction, include it in your inquiry.
3. What is the thermal conductivity of FMA650?
0.021 W/(m·K) at 25℃ (GB/T 10295) and 0.036 W/(m·K) at 300℃ (GB/T 10294). Conductivity rises with temperature, so request the data that matches your mean insulation temperature.
4. What thickness do I need for a 500℃ steam pipe?
FMA650 is the grade to evaluate for 500℃ because FMD450 is rated to 450℃. The thickness depends on pipe diameter, target surface temperature or heat loss, ambient conditions, and available space. Send these and we will calculate it.
5. What thicknesses, width, and roll length are available?
Standard thicknesses are 3, 5, 6, and 10mm, with 15 and 20mm available as custom options. Width is 1500mm. Standard roll lengths are 45m for 3mm, 42m for 5mm, 38m for 6mm, and 30m for 10mm. Other lengths can be customized.
6. Is FMA650 hydrophobic? Does it prevent CUI?
Hydrophobic rate is ≥99% and volumetric water absorption is ≤1%, which helps keep water from collecting against the pipe. No insulation alone prevents CUI; the full system – coatings, cladding, sealed joints, drainage, and maintenance – matters too.
7. Is FMA650 fire resistant?
Burning level is Class A under GB 8624. The classification applies to the standard FMA650 product, not to custom composites.
