3M™ Glass Bubbles iM30K are hollow glass spheres with a typical density of 0.60 g/cc and isostatic crush strength of 27000 psi, providing an additive with a superior strength-to-density ratio for use in injection molding extrusion and sheet molding compounds. They can reduce final part weight by 15% or more without compromising the mechanical integrity.
- Reduce final part weight by 15% or more without compromising mechanical integrity of finished product
- Extremely high strength-to-density ratio glass bubble survives high shear, high pressure processes like injection molding and extrusion
- Faster cooling times of melt processed polymers (injection molding and extrusion), typically 15-25% cycle time improvement
- Improved dimensional stability and reduced warpage and sink marks
