Product Description
Synthetic Foam, Hollow Glass Bubble, HN32HS, Aerospace Adhesives, BoyanCy Material.
Hollow Glass Bubble Features
The trapped air within the bubbles improves acoustic insulation properties by absorbing and dampening sound waves, making them ideal for construction projects requiring noise cancellation. Additionally, hollow glass bubbles enhance the moldability of synthetic foam by reducing viscosity and improving flowability, enabling more efficient manufacturing processes and complex designs.
Applications
- Cushioning: Improves impact resistance and cushioning properties by absorbing and distributing impact energy.
- Packaging: Creates lightweight, durable, and protective packaging for fragile items, reducing shipping costs.
- Automobile Components: Used in lightweight, durable components such as interior trim and acoustic insulation, improving fuel efficiency.
