Product Description
Hollow glass bubbles are an effective thermal insulator because the trapped gas inside the bubbles is a poor conductor of heat. This means that heat transfer through the material is reduced, making it an effective insulator. The thin glass shell also provides additional thermal resistance, further reducing heat transfer.
Key Applications
- Industrial insulation: Improves thermal insulation properties in ceramic fiber insulation and refractory materials, reducing heat loss in high-temperature applications.
- Personal protective equipment: Used in gloves and clothing to provide thermal insulation and protect workers from high temperatures.
