Bonded alumina-zirconia-silica (AZS) with 30% zirconia

Description

Made of alumina-zirconia-silica (AZS) grains. High resistance to glass corrosion. Available in large format with large range of thickness.

Typical application

ERMOLD 300 is dedicated to bottom sub-paving application. Superior resistance to glass corrosion compared to fire-clay or sillimanite materials.

Standard thickness: 150mm and 100mm

Standard sizes: 1000x500mm and 600x500mm.

For application in superstructure, refer to ERMOLD.
