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
Surface salts formed during manufacture are removed via acid washing. This reduces the alkali content and results in a clean surface chemistry compatible with almost any resin system or surface coating. All information provided by Trelleborg Emerson & Cuming |
