Trelleborg AEM Eccospheres® SID-230Z Sodium Borosilicate Glass Microspheres
Categories: Ceramic; Glass; Other Engineering Material; Additive/Filler for Polymer

Material Notes: Eccospheres® glass microspheres are hollow thin-walled glass microspheres composed of sodium borosilicate glass. To the naked eye they resemble a fine, white, free-flowing powder. However, magnification reveals them to be near perfect spheres.

  • High temperature resistance
  • Good density/strength ratios
  • Clean surface chemistry
  • Narrow particle size distribution
  • Low thermal conductivity
  • Low dielectric constant
  • Low dissipation factor

The SID series has the same chemical composition as the SI series, however, due to our unique manufacturing capabilities this series exhibits improved strength, without sacrificing density. High strength ensures survival of the spheres in aggressive processes such as extrusion. All the grades in this series are acid washed to provide a clean surface for either a resin system or surface treatment to bond to.
