Firstly, Let's learn what is Aerogel Blanket ?

Aerogel blankets are highly effective thermal insulation materials due to their low thermal conductivity and lightweight nature. However, selecting the right one requires careful consideration of several factors. Here's a guide to help you make an informed decision:

If you are looking for more details, kindly visit bestlink.

1. Temperature Range:

Operating temperature: Aerogel Blanket has a wide operating temperature range, typically from -200°C to 800°C. Ensure the chosen blanket can withstand the expected temperatures in your application.

Huatao Model can be chosen as below:
We have two series for Aerogel Blanket: One is the HT650 Series, Other is the HT200 Series:
HT650 was Aerogel insulation blanket with fiberglass, similar to Pyrogel XT and Spaceloft ( mainly used for hot &heat insulation and building insulation, working temperature from -200℃ to 650℃), the thermal conductivity from 0.018-0.023 W/m.k
HT200. Aerogel insulation blanket with Aluminium foil, similar to Cryogel Z (mainly used for cold insulation, such as LNG, Working temperature from -190℃-150℃ ), the thermal conductivity from 0.019-0.021 W/m.k

2. Environmental Conditions:

Humidity: Some aerogel blankets (Pyrogel XTE) are sensitive to moisture. If the environment is humid, consider a hydrophobic aerogel blanket. but we also have the hydrophilicity can be chosen.

3. Mechanical Properties:

Compression resistance: Aerogel Blanket can be delicate. If the blanket will experience mechanical stress, select one with sufficient compression resistance.

Flexible: Mainly used for Pipe Insulation, the flexible is necessary.

4. Thermal Conductivity:

R-value: The R-value measures a material's resistance to heat flow. Higher R-values indicate better insulation. Aerogel blankets generally have high R-values.

Specific application: The required R-value depends on the application's heat transfer requirements.  

PS: Enclosed different material's  Thermal Conductivity for your reference：

5. Thickness:

Insulation needs: The thickness of the Aerogel Blanket influences its thermal resistance. Thicker blankets generally provide better insulation.

Space constraints: Consider the available space for installation when determining the thickness.

Huatao Aerogel Blanket thickness range as below:

Model Thickness HT650 3,5,6,10mm HT800 3,5,6,10mm HT200 10mm

6. Cost:

Budget: Aerogel blankets can be more expensive than traditional insulation materials. Compare costs and benefits to determine if the investment is justified. But compare with the Famous Brand, Huatao Aerogel Blanket will be more competitive.

For now, Aspen is the largest manufacturer in the world and with good quality,and at the past 10 years, China is almost blank in the Aerogel Industry, recently years, with the advancement of technology, there was a few factories start the mass production from lab m3 to m3 to m3 right now. in China, there was so few factory have this big ability to provide with big production. China aerogel need to develop the market at such environment, the chinese aerogel factories would like to give a more competitive price to client to instead of the ASPENThis is why our price is interesting for you. and i believe that our quality will make you interesting too.

7. Installation:

Ease of installation: Consider the complexity of installing the aerogel blanket. Some may require special handling or equipment. We have HUATAO Installtion Manul for client to reference. It will be very easy!

8. Certification and Standards:

Compliance: Ensure the aerogel blanket complies with relevant industry standards and certifications (We have the full serise ASTM C which made by SGS, Also own a CE Certificate for European companies)

Here is some SGS Test Report List for your reference:

Additional Considerations:

Fire resistance: Some aerogel blankets are inherently fire-resistant, while others may require additional treatments.

Durability: Consider the expected lifespan of the blanket and its resistance to aging and degradation.

Supplier reputation: Choose a reputable supplier with experience in aerogel technology.

By carefully considering these factors, you can select the most appropriate aerogel blanket for your specific thermal insulation needs.

Mainly Product

As a leading silica aerogel manufacturer in China since , we get new inquiries about aerogel every day. People all around the world are curious about the amazing properties of aerogel. Therefore, we are happy to share the basic knowledge below to help you get the right insight into this wonderful material.

Question 1: What is aerogel?

Answer: Aerogel is a general and collective term for a diverse class of nanoporous structured solid materials, including silica aerogel, which is currently the most widely applied. Most of the time, when we talk about ‘aerogel’, we mean Silica(SiO2) Aerogel.

The 3D network structure of aerogel is composed of nano-size particles, and filled with air or other gases. A typical type of aerogel contains 95-99% air in volume. They are the lowest-density solid materials that have been produced in the world.
Currently, there are more than 30 kinds of materials that can be processed into aerogel structures, but the most commonly seen is Silica(SiO2) Aerogel.

Check this video below to learn more about aerogel.

Question 2: Is aerogel a sticky or adhesive ‘Gel’ material?

Answer: No, aerogel is not sticky or adhesive at all. It is a dry and solid material called ‘solid smoke’ or ‘blue smoke’. 

So why do people call this dry and solid material ‘GEL’? Well, because after the supercritical drying process in aerogel production, the original ‘GEL’ becomes dry and solid, and the finished product is what we call AEROGEL.

Question 3: Is aerogel toxic or harmful to human health?

Answer: No, aerogel is non-toxic and has been proven to be safe for human health. Just it can cause dryness and short-term irritation to human body.

As the most commonly applied aerogel is Silica (SiO2) Aerogel, most of the time, when we talk about ‘Aerogel’, we normally mean Silica (SiO2) Aerogel. Silica aerogel is composed of air and silica(SiO2), no more others. It is 100% inorganic and non-toxic, and has been proven to be safe for human health.
The only thing you need to worry about when handling aerogel is the short-term irritation that aerogel powder(dust) may cause to human body.
Silica aerogel is hydrophobic and may cause dryness and short-term irritation irritation to the skin, eyes, and mucous membranes. Therefore, when handling aerogel, it is recommended to wear respiratory masks, gloves, long-sleeved clothes, safety glasses and even chemical goggles for greater protection. It is also recommended to rinse your body thoroughly after handling aerogel. Single-use overalls are recommended to minimize skin contact.

Question 4: Why is aerogel so special that people say it is future material?

Answer: Because aerogel breaks 15 Guinness World Records for its magical properties, like the lowest thermal conductivity, the lowest density, etc., and people are still studying about different properties of different aerogels. Now more and more people come to realize the super insulation performance of aerogel and choose aerogel insulation as a better thermal insulation solution.

Question 5: What is aerogel material?

Answer: When we talk about ‘Aerogel Material’, normally we mean silica aerogel composite materials like flexible aerogel blankets, rigid aerogel panels, encapsulated aerogel thermal barriers, etc., as well as pure silica aerogel powder/particle.

Question 6: Is aerogel insulation blanket pure aerogel or aerogel composite material?

Answer: Aerogel insulation blanket is a type of aerogel composite material.

When aerogel composited with fiberglass blanket or ceramic fiber blanket, the material shows good mechanical performance and extremely low thermal conductivity, which is better than pure aerogel alone or fiberglass/ceramic fiber blanket alone.

Question 7: Why do people use aerogel composite material instead of 100% pure aerogel for high-efficiency thermal insulation?

Answer: Because 100% pure aerogel is too brittle to be used. It has to be composited with base materials of good mechanical performance such as fiberglass blanket, ceramic fiber blanket, etc.

Question 8: Why is silica aerogel material called ‘the ultimate thermal insulation material in the world’?

Answer: Because silica aerogel features the lowest thermal conductivity. Silica aerogel contains 95% ~ 97% of air, which is trapped in the convoluted matrix of silica. So aerogel can effectively insulate heat against the Three Basic heat flow mechanisms: heat conduction, heat radiation, and heat convection.

Contact us to discuss your requirements of Aerogel Insulation For Sale. Our experienced sales team can help you identify the options that best suit your needs.

Heat Insulation against Heat Conduction
The porous and convoluted nano-structure of aerogels creates extremely long heat transfer path, resulting in high thermal resistance in heat conduction.

Heat Insulation against Heat Radiation
The vast number of nano cells form gas-solid interfaces that prevent heat radiation by reflection, adsorption, transmission, and re-radiation.

Heat Insulation against Heat Convection
The pore size of aerogel is smaller than 70nm in diameter which restricts motion of gas molecules. Therefore, effectively preventing heat transfer through gas convection

Question 9: Is aerogel mass production tech already mature enough for civilian uses?

Answer: Absolutely, yes. Since decades ago, mass production technology of silica(SiO2) aerogel has been mature enough for civilian uses.

The most widely applied property is silica aerogel’s lowest thermal conductivity.
In , our factory Namate created a unique production technique and successfully realized cost-effective industrialization of high-quality silica aerogel and aerogel composites. This unique production technique solved the long-lasting severe dust-drop problem of silica aerogel composites and enhanced the thermal insulation performance to a new level.

Question 10: Why are aerogel materials so expensive? Are they cheaper than 10 years ago?

Answer: Yes, aerogel materials have become much cheaper than 10 years ago. They are expensive because of the high-cost and complicated production process.

For example, in China, aerogel price today is only half that 10 years ago. However, aerogel materials are still much more expensive than conventional thermal insulation materials like rockwool, fiberglass, PU foam, etc. The key reason lies in the high-cost and complicated production process of aerogel.
Generally, there are two steps to make high-quality aerogel:
Step 1. Sol-Gel, and Step 2. Supercritical Drying.
As for the first step, to get a perfect Gel from the Sol, high quality raw materials and highly sophisticated technical operators are essential while the both are quite costly.
As for the second step, the Supercritical Drying process requires high temperature and high pressure during the interaction. The initial investment of such specially designed reactors and the related equipment and devices is very costly. What’s more, to eliminate fluid from the Gel while causing no shrinkage, each small adjustment matters a lot, so it requires very strict and cautious operation. Currently, all around the world, only a few sophisticated and expert-level operators can successfully and consistently handle such delicate operations during daily aerogel mass production.

Question 12: What kind of aerogel materials are widely applied in civilian scenarios?

Answer: Flexible aerogel blanket, rigid aerogel panel, and silica aerogel powder/particles.

12.1 Flexible Aerogel Blanket

• Flexible high-temperature aerogel insulation blanket(≤650℃) is the most commonly-seen aerogel insulation material. It is widely applied for the purposes of energy-saving, fire-prevention, and anti-scald in various industries like the oil&gas, chemical industry, power generation, building construction, etc.
• Cryogenic aerogel insulation blanket(-200℃~+400℃) is widely used for the purpose of energy-saving in cryogenic storage and transportation of LNG, liquid nitrogen, liquid oxygen, etc, and high-clean environments of the pharmacy industry, electronics industry, etc., especially in scenarios where there is only limited space for insulation material installation.

Question 13: What are the advantages and disadvantages of aerogel materials?

Answer:

Advantages of aerogel materials:

• Excellent thermal insulation performance under high temperatures
  With nanoporous silica(SiO2) aerogel as the core material, its thermal conductivity is extremely low even under temperatures up to 650℃.
• Easy installation and extremely low thermal bridge
  Its thermal insulation layer thickness is only 1/5~1/3 of conventional thermal insulation materials. So it is easy to cut and install this insulation blanket and easily lapping over the edges can avoid thermal bridge to the utmost. 
• Hydrophobic 
  Hydrophobic rate≥98%. No water absorption and no moisture absorption. The insulation blanket can prevent pipelines and equipment from CUI and extend their service life.
• Flame retardant
  Flame retardant grade: A grade. It can effectively prevent pipelines and equipment from flame and fire.
• Durable and long service life
  As an aging-resistant inorganic material with a compact and stable material structure and high compression resilience and high hydrophobic rate, this insulation blanket service life can be the same as that of the pipelines and equipment.
• Non-toxic and environmentally friendly
  It does not contain harmful substances such as asbestos, benzene, and formaldehyde, and the whole production process and application process are non-toxic and environmentally friendly. It can be reused after removal so no worry about industrial waste disposal.

Disadvantages of aerogel materials:

• High price
  With the high-cost and complicated production process of aerogel materials, currently, aerogel material price is still much higher than conventional insulation materials like rookwool, fiberglass, PU foam, etc., despite the thinner aerogel insulation thickness in applications.
• Dust-drop problem
  Currently, dust-drop remains a problem in aerogel material applications. Especially in those clean-room requirement working scenarios. To get high thermal insulation performance and solve the dust-drop problem, people have to wrap the aerogel material thoroughly to avoid the influence of aerogel dust on the operators and working environment.

Question 14: What are the most important performances to care about when choosing aerogel materials?

Answer: Thermal conductivity, working temperature range, dust-drop rate, hydrophobicity, burning characteristics, density, flexibility/stiffness, etc.

Thermal conductivity

Low thermal conductivity is the most important reason why people choose areogel materials. Most silica aerogel material thermal conductivity is now around 0.020 at 25℃. While some high-quality aerogel material can even reach ≤0.015 at 25℃. When applied in high-temperature scenarios, aerogel thermal conductivities at different temperatures are considered as the most important.

Working temperature range

There are different aerogel materials for different working temperature ranges. The most popular one is for the working temperature range up to 650℃(Click here to check details about our ThermFelt HT650 series). There is also aerogel material specially designed for cryogenic insulation, which can withstand a temperature range -200℃ to +500℃(Click here to check details about our CryoFelt LD). Another special aerogel material is meant for super-high-temperature applications above ℃(Click here to check details about our ThermFelt SHT series)

Dust-drop Rate

Another important performance people care about is the dust-drop rate of aerogel material. Now all the silica aerogel composite materials are faced with the aerogel-dust-drop problem. Because after the super-critical drying process, there is inevitably some aerogel dust residue on the surface. Aerogel dust can cause dryness and irritation problems to human skin and make the working environment unclean. Fortunately, years ago, we successfully developed the low-dust-drop version aerogel insulation material, and after years of development, now the dust-drop rate has been proven to be the lowest among all the aerogel brands in the world.

Hydrophobicity

Generally, for working temperatures below 200℃, normal aerogel materials(qualified aerogel materials, not defective or fake ones) can remain hydrophobic. When the temperature goes up to 300℃ or even above, only the ASTM standard aerogel materials can remain hydrophobic.

Burning characteristics

Qualified aerogel materials must be tested as non-flammable and non-smoke when burning or heating. Check our ASTM testing report

Density

Density is another specification to care about. Most aerogel material density is between 150 to 200kg/m3. If with the same base material, the lower density, the higher aerogel percentage, which means the better aerogel material.

Flexibility/stiffness

Flexibility/stiffness is another performance to care about. Application scenarios like small-size pipeline thermal insulation normally require ultra-flexible aerogel material for easy installation. Many high-temperature equipment insulation scenarios require higher stiffness for better mechanical strength.

Question 15: What’s the relation between insulation thickness, thermal conductivity, and thermal insulation effect of aerogel materials?

Answer:

Thermal conductivity is the property of the aerogel material type itself, and has nothing to do with insulation thickness;

With the same aerogel material type(the same thermal conductivity), the thicker insulation thickness, the better thermal insulation effect;
