Glass bubbles can be used in high-temperature applications due to their unique properties. These hollow spheres, made from soda-lime borosilicate glass, offer advantages such as low density, high crush strength, and excellent thermal stability.

In high-temperature applications, glass bubbles can be used as:

  1. Thermal Insulation: Glass bubbles have low thermal conductivity, making them ideal for insulating materials against high temperatures. They can be added to polymers, coatings, and composites to improve their thermal insulation properties.
  2. Fillers for Lightweight Materials: Glass bubbles can be used as fillers in materials that need to withstand high temperatures, such as syntactic foams and lightweight cement composites. They reduce the density of the material without compromising its thermal stability.
  3. Expansion Joints: Glass bubbles can be used in expansion joints to provide flexibility and thermal resistance. They can accommodate thermal expansion and contraction without causing damage to the structure.
  4. Fire Protection: Glass bubbles can be incorporated into fire-resistant materials to enhance their thermal properties. They can help to reduce heat transfer and improve the material’s ability to withstand high temperatures.

When using glass bubbles in high-temperature applications, it is important to consider their temperature resistance, compatibility with other materials, and the specific requirements of the application.
