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:
- Burnish resistance: due to its hardness of 6 on Mohs scale, milled E-glass provides good burnish resistance (low tendency to become glossy when rubbed).
- Ease of tinting: due to the combination of refractive index, brightness and color, paints including fine milled E-glass particles will provide excellent reproducible colour results when working with tinting systems.
- Gloss control: the gloss level of an interior coating can be influenced by selecting the appropriate grade of milled E-glass.
- Scrub resistance: due to its hardness of 6 on Mohs scale, milled E-glass improves wet-scrub resistance of interior decorative paints.
- Stain resistance: milled E-glass acts as a supporting mineral filler in stain resistant coatings.
