High Silica Glass Marble
CYC High Silica Glass Marbles are belonging to Na₂O-B₂O₃-SiO₂ glass
which is designed for manufacturing fine high silica glass fiber
and high silica glass wool particularly. Our high silica glass
marbles’ quality control is under ISO 9001:2008 standard. It is
widely used in special glass fiber enterprises over China and
abroad, such as USA, Russia and Belarus so on. The production
capacity is around 40000 tons per year.
Glass marble balls are round & smooth
No visible deformed or defective glass marble balls
No impurities affect the production
No air bubbles in glass marble balls
