Ultralight TPO Technology Enabled by Long Polymer Fibres, Glass Bubbles and Microcellular Foam Injection Molding
Presented by Ms Anita Hajetian, Senior Applications Engineer, 3M Australia


Hollow glass microspheres, or Glass Bubbles, have been added to plastics for several years to reduce weight to improve fuel economy and lower the carbon footprint of vehicles.  The addition of stiff, hollow glass spheres makes the plastic composite stiffer and therefore tends to reduce impact strength, especially cold temperature impact strength.  A novel combination of Glass Bubbles and polymer fiber has been developed in a polypropylene matrix composite to improve the impact strength and provide even more weight reduction compared to talc filled TPO materials.

Keywords: Thermoplastics, Weight reduction, Improved impact strength
