Precise glass beads

Description:

Precise Glass beads was made from glass sand which crushed by glass blocks and plate glass,fused by high tempreture in the electric furnace.

Precise Glass beads is not only with low heat conduction,nice strength,good chemical stability,but also carfully picked with precision tolerance demand for different usages.
