Trelleborg AEM Eccospheres® IG-101 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. Properties High temperature resistance Good density/strength ratios Clean surface chemistry Narrow particle size distribution Low thermal conductivity Low dielectric constant Low dissipation factor Specifically developed for industrial applications the IG series of Eccospheres® glass microspheres are manufactured to the same high standards as other series. This range does not undergo final washing or floating processes. All information provided by Trelleborg Emerson & Cuming
