  • Reduces warpage and sink marks while improving dimensional stability

3M™ Glass Bubbles iM Series are specially formulated for a high strength-to-weight ratio. This makeup allows for enhanced survivability under demanding processing conditions like injection molding. They are also engineered to produce stable voids, which help result in low thermal conductivity and a low dielectric constant. Help improve strength and performance with 3M™ Glass Bubbles iM Series.

3M™ Glass Bubbles are hollow, water-resistant, and chemically-stable soda-lime-borosilicate glass microspheres that are engineered to serve as an alternative to conventional fillers and additives like silica, calcium carbonate, talc, and clay. These low-density particles are used in a wide range of industries to help reduce part weight, lower costs, and enhance product properties. Because of their unique spherical shape, they also offer a number of important benefits, including higher filler-loading, lower viscosity/improved flow, and reduce shrinkage/warpage. Discover how 3M™ Glass Bubbles can be mixed in with a variety of compounds to be sprayed, cast, and/or moulded with incredible results.

Suggested Applications

  • For use in applications such as injection molding and extrusion
  • Use as an alternative to conventional fillers and additives like silica, calcium carbonate, talc, and clay
