Trelleborg AEM Eccospheres® SID-311Z Sodium Borosilicate Glass Microspheres

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.PropertiesHigh temperature resistanceGood density/strength ratiosClean surface chemistryNarrow particle size distributionLow thermal conductivityLow dielectric constantLow dissipation factorThe 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.All information provided by Trelleborg Emerson & Cuming
