Hollow Glass Bubble Description
Injection Molding, Hollow Glass Bubble, HN46, Thermoplastic, Thermal Insulation.
The hollow glass bubbles are added to polymer materials in powder or pre-mixed compound form. These bubbles act as filler material, reducing weight while maintaining structural integrity. They can significantly decrease the weight of final products while improving dimensional stability by reducing shrinkage and warpage. The trapped air inside the bubbles helps dissipate heat more evenly during cooling, preventing uneven cooling effects. The low coefficient of thermal expansion of the glass bubbles further enhances dimensional stability.
Applications
- Medical devices: Used in injection-molded medical devices like syringe barrels and drug delivery systems to reduce weight and improve mechanical properties, resulting in more reliable and comfortable patient solutions.
- Packaging: Incorporated into injection-molded packaging materials such as containers and trays to reduce weight and enhance dimensional stability, leading to better product protection and extended shelf-life.
