Glass Bubbles for sheet molding composites

3M™ Glass Bubbles for sheet molding composites

CONTACT A 3M EXPERT

Sheet molding composites (SMCs) are well known for being more light weight than metals or other types of composite materials. Now, compounders and resin suppliers can produce SMC parts that are up to 40% lighter, enabling ultralightweight sheet molding composites that replace heavier steel and aluminum body panels, hoods, trunk lids and more. That’s because 3M™ Glass Bubbles – tiny, hollow glass microspheres added to resins in SMC production – are engineered to withstand the requirements of the sheet molding process despite their low density. Best of all, they help enable your parts to meet OEM requirements for Class A paintable surfaces.

      Weight reduction: 3M™ Glass Bubbles can enable densities below 1.0 g/cc and a total SMC component weight reduction of 45%, making ultralightweight SMC parts a replacement for metal in more places on the vehicle.

      Class A paintable finishes: While fillers can sometimes affect the final part surface, compounders and resin suppliers can still produce lightweight SMCs with a Class A Paintable finish – making SMCs/BMCs a replacement in many more places on the vehicle.
