Product Description

Aerogel blanket is a type of insulating material made from aerogel, which is a lightweight solid material derived from gel in which the liquid component has been replaced with gas. Aerogels are known for their incredibly low density, high porosity, and excellent thermal insulating properties.

Exceptional Insulation: Aerogel blankets provide superior thermal insulation due to their low thermal conductivity. This property is crucial for applications requiring effective temperature control, such as in building insulation, aerospace, and cryogenics.

Lightweight: One of the standout features of aerogel blankets is their incredibly low density, often less than 0.1 g/cm³. This lightweight nature allows for easy handling and application, particularly in industries where weight savings are critical.

High Porosity: Aerogel blankets possess a highly porous structure, which contributes to their insulating performance while also allowing them to be flexible and easily shaped to fit various applications.

Hydrophobicity: Many aerogel blankets are designed to be hydrophobic, meaning they repel water. This property helps maintain their insulating efficiency in damp or humid environments.

Thermal Stability: Aerogel blankets can withstand extreme temperatures, ranging from cryogenic conditions to high-temperature environments, making them suitable for a variety of industrial applications.

Q: What is the thermal conductivity of aerogel blankets at 25°C, and why is it significant?

A: The thermal conductivity of aerogel blankets ranges from 0.018 to 0.057 W/m·K at 25°C. This low thermal conductivity is significant because it indicates that aerogel blankets provide excellent insulation, minimizing heat transfer and enhancing energy efficiency in various applications.

Q: In what forms are aerogel blankets available, and what are the benefits of each?

A: Aerogel blankets are typically available in roll or mat forms. Rolls are advantageous for large area applications, allowing for continuous coverage, while mats can be used for specific shapes or smaller areas. Both forms maintain the unique insulating properties of aerogel.

Q: What is the temperature range that aerogel blankets can withstand, and what applications benefit from this feature?

A: Aerogel blankets can withstand temperatures from 1°C to 650°C. This broad temperature range makes them suitable for various applications, including building insulation, aerospace, and industrial processes where high heat resistance is essential for safety and performance.

Q: How does the hydrophobicity of aerogel blankets contribute to their performance?

A: Aerogel blankets have a hydrophobicity rating of ≥ 99.5, meaning they repel water effectively. This feature prevents moisture absorption, ensuring that the insulating properties remain intact even in humid conditions, thus prolonging the lifespan of the material.

Q: What thickness options are available for aerogel blankets, and how do they impact their use?

A: Aerogel blankets come in thicknesses of 3, 5, 6, and 10 mm. Thicker blankets generally provide better insulation, making them suitable for extreme temperature applications, while thinner options may be preferred for lighter-weight applications or areas where space is limited.

Q: What is the significance of the density and tensile strength of aerogel blankets?

A: Aerogel blankets have a density of ≤ 200 kg/m³ and a tensile strength ranging from 800 to 1000 kPa. The low density contributes to their lightweight nature, making them easy to handle, while the high tensile strength ensures durability and resistance to mechanical stress in various applications.
