HCMS-W

ELMINAS SPHERES® HCMS-W are high-quality ceramic hollow microspheres, serving as functional lightweight fillers.

ELMINAS SPHERES® HCMS-W are characterized by very high thermal and mechanical stability and bright color. They are available in various grain fractions.

Features and Benefits :

  • Non-combustible.
  • Chemically inert.
  • Temperature resistant up to 1600°C.
  • Excellent acoustic and thermal insulation.
  • Reduced density/ reduced weight of final products.
  • Improved mechanical properties including impact strength and dimensional stability.
  • Improved thermal-shock resistance.
  • Improved flow and working properties.
  • No water absorption under pressure.

Application Recommendation : 

ELMINAS SPHERES® HCMS-W should be incorporated into the system at the end of processing. Only a short blending time is necessary to attain a homogenous dispersion. We recommend the use of a ribbon blender or a plougshare mixer for dry blends.

Application Fields : 

 

  • Abrasives

  • Automotive 

  • Construction Chemistry

  • Insulation

  • Paints and Coatings

  • Plastics
