Hollow Glass Beads Description
Hollow Glass Beads are small spherical particles made of glass with a hollow structure inside. They are typically made from high-silicate or other specialized glass materials, offering extremely low density and high strength. Their main characteristics include lightweight, high strength, excellent chemical stability, high-temperature resistance, and corrosion resistance. The outer diameter of standard-grade hollow glass microspheres are customized according to users, with the hollow interior occupying a large portion. This structure provides excellent thermal insulation, soundproofing, buoyancy, and compression resistance properties.
SAM can customize Hollow Glass Beads with different densities, pressures, and particle sizes according to customer needs to meet the special requirements of different customers.

FAQs
Q1: What are the key properties of Hollow Glass Beads?
Hollow Glass Beads are known for their low density, high strength-to-weight ratio, high compressive strength, thermal and acoustic insulation properties, chemical stability, and resistance to high temperatures. These beads also offer excellent floatation properties and high-pressure resistance.
Q2: How do Hollow Glass Beads improve material properties?
These beads improve the properties of materials by reducing the weight while maintaining strength, enhancing thermal insulation, improving soundproofing qualities, and increasing the durability and buoyancy of materials.
Q3: Are Hollow Glass Beads environmentally friendly?
Yes, Hollow Glass Beads are considered environmentally friendly as they are made from natural materials and are fully recyclable. They do not contain harmful substances and can be used in applications that promote sustainability.
Q4: Are there different types of Hollow Glass Beads?
Yes, Hollow Glass Beads come in various sizes, densities, and grades depending on the specific application requirements. At Stanford Advanced Materials, we offer three types of Hollow Glass Beads:
- Standard Grade: Ideal for general applications where moderate strength and performance are required.
- High-Performance Grade: Designed for more demanding applications requiring superior strength, durability, and performance.
- Custom Grade: Tailored specifically to meet the unique requirements of a particular application, including customized sizes, densities, and other properties.
