Trelleborg AEM Eccospheres® FTD-200 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 The FTD series are washed to remove surface salts, this results in an ideal surface topography for resins or surface treatments to key. The clean ion exchanged surface ensures compatibility with almost any resin system and in particular this series is recommended for sulphur sensitive systems.
