Engineered additives

3M™ Glass Bubbles are hollow microspheres made of chemically stable soda-lime borosilicate glass. These density-reducing additives help plastics manufacturers produce lighter weight parts in order to achieve stringent fuel economy targets for automotive and aerospace manufacturers. They also provide significant productivity benefits, including shorter cycle times, enhanced dimensional stability and less warpage – helping to reduce waste and improve throughput.

Polymer processing with glass bubbles

This seminar will address how to calculate optimal glass bubble loadings for your resin system and your process, from twin screw extrusion to injection molding. Learn how to fine-tune your process to ensure optimum glass bubble survival and improve
