Polymer Composites with Hollow Glass Microspheres: Processing, Properties and Applications
Date: Nov. 6, 2012 – 11:00 AM CST
Low-density, high-strength 3M™ Glass Bubbles can provide significant lightweighting and processing benefits for a variety of resin systems. Learn how to ensure microsphere survival in high-shear processes…shorten mold cycle times…and optimize materials for weight savings and other desirable properties with effective formulation guidelines.
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.
