Details
  • Additive used for density reduction in sheet and bulk molded composite vehicle parts
  • Helps reduce weight of composite parts by up to 40 percent with a density below 1.0g/cc
  • Allows greater density reduction at lower filler loadings to maintain composite strength
  • Enables parts with Class A paintable finishes
  • Can significantly help improve fuel economy and extend electric vehicle battery range
  • Spherical shape and moderate hardness help reduce production equipment wear
  • Enables production of ultra-lightweight composite parts that may offer a lower cost alternative to aluminum in many applications

Glass Bubble Benefits
3M™ Glass Bubbles S32HS offer a number of competitive advantages over traditional polymer fillers like silica, calcium carbonate, talc or clay. By replacing conventional fillers, these hollow glass microspheres can help reduce the weight of molded parts by up to 40 percent. With a density of 0.32 g/cc and an isostatic crush strength of 6,000 psi, 3M glass bubbles S32HS are great for customers looking to reduce composite density below 1.0 g/cc without sacrificing mechanical integrity or surface aesthetics. Furthermore, the unique spherical shape of our glass bubbles allows for higher volume loading while maintaining workable viscosity and contributes to the production of Class A paintable surfaces.

A Lighter Future
A typical automobile has about 300 kg (661 lbs) of composite parts that contribute to vehicle weight. With electric and high efficiency vehicles becoming more popular, reducing that weight is the key to staying competitive. By integrating our glass bubbles into their sheet and bulk molded composite parts, customers can significantly improve a vehicle’s fuel economy or battery range. In some cases, using ultra-light composite parts may even be more cost effective than aluminum in the right applications.
