Milled E-glass (glass (amorphous silica) consisting of SiO2, Al2O3, CaO, MgO, B2O3, F2, Na2O, K2O, Fe2O3) is produced from an industrial E-glass side stream. Milled E-glass can be characterised by:
- ‘Green’ attributes, as a product of an industrial side stream.
- Relatively high Mohs hardness of 6.
Advantage over quartz and cristobalite and certain feldspar grades: free of labelling, milled E-glass grades can be used as an alternative when labelled grades of other mineral fillers are no longer permitted or wanted.

Milled E-glass will provide:
- Abrasion resistance: due to its hardness of 6 on Mohs scale, milled E-glass will increase the coating’s resistance to wear of a coating.
- Clarity: due to its fairly low refractive index, milled E-glass becomes transparent when combined with certain binder systems.
