Product Description
Artificial Stone, Hollow Glass Bubble, HN38, Thermoplastic, Tooling Board
Hollow Glass Bubble Description
The addition of hollow glass bubbles improves Artificial Stone's compressive strength, flexural strength, and impact resistance. Additionally, hollow glass bubbles make artificial stone easier to shape and mold into other forms.
Hollow Glass Bubbles Applications
- Lightweight concrete: Used as a lightweight filler material to reduce weight and improve thermal insulation properties.
- Insulating materials: Component in spray foam and rigid foam insulation to enhance thermal insulation.
- Plaster and stucco: Lightweight filler that improves workability and reduces weight.
