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