Product Description
Hollow glass bubbles, also known as glass microspheres, serve as lightweight fillers in composite materials like syntactic foam and lightweight concrete. These microspheres provide exceptional properties including light weight, low thermal conductivity, and superior resistance to compressive stress compared to other foam materials.
Key Applications
- Plaster and stucco: Used as lightweight filler to reduce weight and improve workability in interior/exterior walls, ceilings, and decorative features
- Insulation: Enhances thermal and acoustic properties in insulation boards and coatings
