- 3M Product Number iM16K
- 3M ID FS910054329
- UPC 04046719782048
Details
Highlights
- Density reduction leading to high weight reduction
- Better strength-to-density ratio providing a consistent weight reduction and high crush strength assuring the survival of Glass Bubbles during the harsh processing conditions
- Improved dimensional stability which translates to less warpage of finished parts in the plastic injection molding process
- Smaller particle size particularly important for class A finishing automotive parts
- Chemical stability and inertness
- Temperature resistance
3M™ Glass Bubbles iM16K are engineered hollow microspheres made of soda-lime borosilicate glass with a density of 0.46 g/cm³ and an excellent isostatic crush strength of 16,000 psi / 1100 bar.
The iM16K grade provides an additive with outstanding strength-to-density ratio for use in injection moulding, extrusion, and sheet molding compounds. The iM16k Glass Bubbles feature a very small medium particle size of 20 µm.
