Eccospheres®

Eccospheres®

Eccospheres® are thin-walled, hollow glass microspheres (HGMS) developed to meet the demanding strength, weight and electrical specifications of our customers. Magnification reveals the near perfect spherical shape of HGMS, which to the naked eye, resemble a fine, white, free-flowing powder.

High temperature resistance

Good density to strength ratios

Low thermal conductivity

Customized saline treatments available

Key Applications

Eccospheres®can be incorporated into a wide range of polymer and resin systems and can replace or combine with other materials to create composites.

Chemically sensitive systems

High viscosity systems

Extreme processing conditions

Low dielectric or loss tangent

High temperature systems

FTD Series

The FTD series exhibits a clean ion-exchanges surface that ensures compatibility with almost any resin system.

The FTD series has a basic surface chemistry with no sulfur content, which makes it perfect for sulfur sensitive chemistries.

SI Series

The SI series exhibits a clean surface chemistry with a reduced alkali content ensuring compatibility with most resin and surface coating systems.

SID Series

The SID series exhibits a clean surface chemistry with improved strength. High strength ensures survival of the sphere when subjected to aggressive processing. This series has the highest strength to weight ratio.
