How to Lower Thermal Conductivity with Polymeric MicrospheresEnergy savings is always an important topic and of high importance to many companies and consumers.  Polymeric microspheres are composed of a thermoplastic shell encapsulating hydrocarbons, which is expandable after heating and will form an inflatable closed cavity with a good insulative value.

When adding only 1.5% by weight of expanded microspheres combined with thermo insulative coatings you can effectively reduce your thermo conductivity by 50%.

Besides reducing your thermo conductivity you can also achieve:

  • Cost savings
  • Reduced dry times
  • Matt surfaces
  • Storage stability
  • Lower water absorption.

The addition of only 1% by weight of expanded microspheres can not only reduce the density of your coating by about 5%, but also significantly enhance the stereoscopic feeling of the coating.

It is also easier to obtain a thicker coating effect with- out cracking.

If lower thermal conductivity, costs, and densities are goals of your project consider Dualite Polymeric Microspheres.  Please contact Chase Corporation for technical guidance in choosing the right microsphere for your project.
