Glass bead ： Types of Glass Microspheres
Glass microspheres come in various types based on their application, shape, composition, and size:
1. Hollow Glass Microspheres: These have a lightweight, low-density, hollow structure, offering excellent insulation and soundproofing. They are ideal for thermal insulation materials, fillers, and reflective road paints. They are also used in construction materials to reduce weight while maintaining insulation and soundproofing properties.
2. Solid Glass Microspheres: These have a solid structure and higher density than hollow microspheres. They are used in road markings, sandblasting, surface treatments, and as fillers and reflective materials in paints and coatings.
3. Nano-Scale Glass Microspheres: With a uniform particle size distribution, these microspheres are used in sandblasting, surface treatments, paints, coatings, and as fillers. Their particle size typically ranges from 1 to 100 micrometers.

Glass bead Application
1. Cosmetics: Glass microspheres enhance the texture and glossiness of cosmetics due to their reflective properties and smooth surface. glass beads are used in skincare products, eyeshadows, foundations, and more.
2. Building Materials: Thanks to their insulation properties, strength, and reflective capabilities, glass bead are incorporated into building materials such as plaster, cement, and wall coatings.
They are used in insulation and soundproofing materials and added to paints to increase reflectivity, making them ideal for road markings and signage.
3. Oil and Gas Wells: In oil and gas drilling, glass bead are used in pressure fluids and muds as proppants to support the wellbore and enhance oil and gas extraction.
4. Grinding and Polishing: Due to their hardness and wear resistance, glass microspheres are employed in grinding and polishing processes. They are used to smooth surfaces in the manufacturing of cars, ships, and airplanes.
5. Fillers: Glass microspheres serve as fillers in plastics and rubber, reducing product weight while enhancing mechanical properties, thermal stability, and appearance.
6. Road Markings: Their reflective properties make glass microspheres widely used in road paints, significantly improving nighttime visibility and driving safety.
7. Crafts and Decorations: Colored glass microspheres are used in clothing decoration and floral crafts to create a flowing sand effect.
8. Anti-Sedimentation Agent: Like organic bentonite clay, glass microspheres prevent pigments and fillers from settling, maintaining a uniform distribution.
