Product Description
Thermoplastic, Hollow Glass Bubble, HN32HS, Synthetic Material, BoyanCy Material.
Hollow Glass Bubble Benefits
The use of hollow glass bubbles in thermoplastics improves surface finish, resulting in a smoother and more consistent appearance. The addition of hollow glass bubbles significantly reduces thermal conductivity due to the trapped air within their spheres, preventing heat transfer through the material. When incorporated, they create a network of air pockets that reduces the amount of solid material available for heat transfer, enhancing thermal insulation properties.
Key Applications
- Packaging: Used in lightweight, durable packaging materials like containers and trays, reducing shipping costs and improving sustainability.
- Electronics: Incorporated in thermoplastic components for devices like computer cases and smartphone covers, improving portability and reducing damage risk.
