FAQ
1.What is the difference between hydrophobic and conventional silica aerogel powder?
Hydrophobic aerogel powder undergoes surface modification, making it water-repellent and moisture-resistant. This ensures stable thermal performance even in humid or condensation-prone environments.
2.What is the typical particle size range?
The standard particle size ranges from 5 to 50 μm, with customized distributions available upon request.
3.Does high humidity affect its insulation performance?
No. Due to its hydrophobic surface, water absorption is extremely low (typically <1%), ensuring consistent insulation performance in high-humidity environments.
4.Can it be directly added to coatings or resin systems?
Yes. It can be used as a functional filler. Proper dispersion techniques (e.g., high-shear mixing) are recommended for optimal performance.
