Product Description
HN40 Hollow Glass Microspheres are engineered for oil well cementing, thermal insulation materials, and deep sea insulation pipes. These hollow glass bubbles offer exceptional performance in demanding applications.
About Hollow Glass Bubbles
Hollow glass bubbles, also known as glass microspheres or glass bubbles, are tiny, hollow spheres made of glass. They are typically between 10 and 200 micrometers in diameter and are used in a variety of applications due to their unique properties.
Additional functionalities, such as silane coatings, are commonly added to increase the matrix/microspheres interfacial strength. Microspheres made of high quality optical glass can be produced for research on optical resonators or cavities.
Key Applications
- Oil and Gas Industry: Added to drilling fluids and cement slurries to reduce density and improve thermal insulation properties
- Coatings and Paints: Improves durability, scratch resistance, and creates textured surfaces while enhancing fluidity
- Packaging: Enhances insulation and cushioning properties while maintaining protective appearance
