Description

3M™ Glass Bubbles iM16K are hollow glass spheres with a typical density of 0.46 g/cc and isostatic crush strength of 16000 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
