3M™ Glass Bubbles for Injection Moulding & Extrusion

Are you producing plastics for the automotive and aerospace market sectors? Are you looking to reduce the weight of your plastic components, improve their dimensional stability or improve processing times benefiting both productivity and profits?

In that case, we would like to spotlight the 3M™ Glass Bubbles for injection moulding and extrusion applications.

3M™ Glass Bubbles are advanced, low-density additives that can be used in a variety of different industrial applications. They are available in a wide range of densities and crush strengths, which are capable of surviving the most demanding compounding and injection moulding processes even at pressures of up to 30,000 psi. Moreover, 3M™ Glass Bubbles are compatible with all common thermoplastics, including polypropylene, nylon, ABS, and others.

These microscopic spheres of soda-lime/borosilicate glass are water insoluble, chemically stable, and offer a high strength-to-weight ratio.

3M™ Glass Bubbles can be used to reduce the density of thermo-elastic parts which may be critical to plastics companies operating within the transportation supply chain where OEM’s are seeking to meet strict light-weighting targets for their automotive vehicles and airplanes.

Indeed, they can help plastics processors to:

  • Reduce final part weight by 15% or more
  • Increase productivity with a 15-25% reduction in injection moulding cycle time
  • Maintain or improve dimensional stability and other physical properties
  • Reduce shrinkage and warpage
  • Contribute to sustainability through better fuel economy
