Product Overview
AIRG-1020ME is a 1–2 mm hydrophobic silica aerogel granule grade developed for thermal insulation materials, lightweight composite systems and engineered formulations requiring a defined millimeter-scale aerogel structure.
The material combines low thermal conductivity, low bulk density and a highly porous nanoscale structure with hydrophobic surface characteristics. Its controlled 1–2 mm granule size provides a practical option for material systems where larger aerogel particles are preferred over finer AIRG-ME grades.
Within the AIRG-ME series, AIRG-1020ME is positioned between the 0.5–1 mm AIRG-0510ME grade and the larger 2–3 mm AIRG-2030ME grade, providing an intermediate particle-size option for different insulation materials and processing requirements.
Why Choose AIRG-1020ME?
AIRG-1020ME provides a defined 1–2 mm granule size together with the lightweight, highly porous and low-conductivity characteristics of hydrophobic silica aerogel.
The intermediate granule size provides an additional selection option where material developers need a larger granular structure than AIRG-0510ME while remaining finer than AIRG-2030ME.
Grade selection should be based on the required particle size, processing method, packing structure, surrounding materials and target properties of the finished system.
Key Performance Features
Controlled 1–2 mm Granule Size
AIRG-1020ME provides a defined 1–2 mm particle-size range for applications where larger aerogel granules are preferred over finer AIRG-ME grades.
Low Thermal Conductivity
With thermal conductivity below 0.018 W/(m·K) at 25°C, AIRG-1020ME provides a thermally insulating aerogel component for compatible insulation and composite materials.
Highly Porous Aerogel Structure
A porosity of 90–95% and BET surface area of 600–800 m²/g reflect the highly porous internal structure of the silica aerogel network.
Low Bulk Density
With a bulk density of 80–100 kg/m³, AIRG-1020ME retains the characteristic lightweight structure of silica aerogel in a millimeter-scale granular form.
Hydrophobic Surface
AIRG-1020ME features hydrophobic surface characteristics that reduce affinity for liquid water. This material property can be beneficial in systems where moisture exposure is a consideration, although the moisture performance of the finished product depends on the complete material and system design.
What Makes AIRG-1020ME Different?
AIRG-1020ME is distinguished primarily by its controlled 1–2 mm granule size within the AIRG-ME series.
Compared with AIRG-0510ME, which has a particle-size range of 0.5–1 mm, AIRG-1020ME provides a larger granular structure. Compared with AIRG-2030ME, which has a particle-size range of 2–3 mm, AIRG-1020ME provides an intermediate particle-size option.
This positioning makes AIRG-1020ME suitable for material systems where the 1–2 mm range better matches the required processing conditions, packing structure and finished-material design.
AIRG-ME Series Particle Size Options
AIRG-ME hydrophobic silica aerogel granules are available in four standard particle-size grades:
| Grade |
Particle Size |
| AIRG-0105ME |
0.1–0.5 mm |
| AIRG-0510ME |
0.5–1 mm |
| AIRG-1020ME |
1–2 mm |
| AIRG-2030ME |
2–3 mm |
AIRG-1020ME occupies the intermediate particle-size position between AIRG-0510ME and AIRG-2030ME. The appropriate grade should be selected according to the required particle size, material structure, processing method and application requirements.
Frequently Asked Questions
What is AIRG-1020ME?+
AIRG-1020ME is a 1–2 mm hydrophobic silica aerogel granule grade developed for thermal insulation materials, composite systems and engineered formulations requiring a defined millimeter-scale aerogel structure.
What is the particle size of AIRG-1020ME?+
AIRG-1020ME has a specified particle-size range of 1–2 mm. Within the AIRG-ME series, it is positioned between AIRG-0510ME at 0.5–1 mm and AIRG-2030ME at 2–3 mm.
Is AIRG-1020ME hydrophobic?+
Yes. AIRG-1020ME has hydrophobic surface chemistry that reduces its affinity for liquid water. Hydrophobicity of the aerogel material itself does not mean that a finished insulation system is automatically waterproof. Overall moisture performance also depends on surrounding materials, construction and system design.
How does AIRG-1020ME differ from AIRG-0510ME?+
The primary difference is particle size. AIRG-0510ME has a particle-size range of 0.5–1 mm, while AIRG-1020ME provides larger 1–2 mm granules. Grade selection should consider the particle-size requirements, processing method and structure of the intended material system.
How does AIRG-1020ME differ from AIRG-2030ME?+
AIRG-1020ME has a particle-size range of 1–2 mm, while AIRG-2030ME provides larger 2–3 mm granules. AIRG-1020ME therefore provides an intermediate particle-size option between AIRG-0510ME and AIRG-2030ME.
What is the thermal conductivity of AIRG-1020ME?+
AIRG-1020ME has a specified thermal conductivity of <0.018 W/(m·K) at 25°C. Thermal performance in a finished material depends on factors including formulation, aerogel content, material density, packing structure, processing conditions and overall system design.
What are the porosity and BET surface area of AIRG-1020ME?+
AIRG-1020ME has a specified porosity of 90–95% and BET surface area of 600–800 m²/g. These parameters characterize the highly porous internal structure of the silica aerogel material.
Are 1–2 mm granules the same as 1–2 mm pores?+
No. The 1–2 mm value refers to the external size of the aerogel granules, not the internal pore size. AIRG-1020ME has a nanoscale internal porous structure with a specified mean pore diameter of <30 nm. External granule size and internal pore diameter therefore describe different structural characteristics of the material.
Does a larger granule size mean lower thermal insulation performance?+
Not necessarily. Particle size and intrinsic thermal conductivity describe different material characteristics. AIRG-1020ME has a specified thermal conductivity of <0.018 W/(m·K) at 25°C. Performance in a finished insulation material additionally depends on formulation, packing structure, material density, surrounding materials and system design.
Is AIRG-1020ME a finished insulation product?+
No. AIRG-1020ME is a silica aerogel material intended for incorporation into compatible thermal insulation materials, composite systems and engineered formulations. The performance of the finished product depends on its complete material composition, manufacturing process and system design.
How should AIRG-1020ME be selected relative to other AIRG-ME grades?+
Particle size is one of the primary considerations when selecting between AIRG-ME grades. AIRG-1020ME provides the 1–2 mm option for material systems requiring a larger granular structure than AIRG-0510ME while remaining finer than AIRG-2030ME. Final selection should also consider processing conditions, packing requirements, surrounding materials and target properties of the finished product.
Can AIRG-1020ME samples be evaluated before bulk purchasing?+
Yes. Sample evaluation is recommended to determine whether the 1–2 mm granule size is appropriate for the intended material formulation and processing method. Customers can provide their intended application, processing method and target material requirements when requesting product-selection support.
Application results should be verified under the customer's actual formulation, process and service conditions. Material-level technical clarification, sample evaluation support and documentation support are available where appropriate.
