Glass-ceramic: SCHOTT NEXTREMA® chemical resistance
Surface highly resistant to chemical attacks by acids and bases
This glass-ceramic material platform is resistant to acids and bases: NEXTREMA® is chemically resistant to acids and bases and a reliable material even in these aggressive environments. It meets all subsequent ISO and DIN standards in its chemical resistance to acids, bases and hydrolytic influences. The elimination of degradation enables reliable material behavior as well as stable process environments even under typical corrosive conditions. Such chemically resistant and base resistant glass-ceramic is used in all fields of industrial and product design.
Here are further details of the chemical properties:
Principal constituents (reference: DIN EN 1748-2-1)
The principal constituents of all the ceramic materials are as follows:
The principal constituents of all the ceramic materials are as follows:
| The materials do not contain any harmful substances according to the European directive 2002/95/EC “Hazardous Substances in electrical and electronically Equipment” and fulfill the terms of RoHS without any concerns. |
|
| Federal Republic of Germany waste disposal regulations differentiate five classes of waste, Z0 (non-restricted disposal), Z3 (household waste), and up to Z5 (highly toxic waste). All NEXTREMA® materials are classified as non-restricted disposal. Local government regulations may differ. Please contact the local authority if needed. NEXTREMA® must not be disposed of in recycling boxes for standard glass (e.g. glass bottles). |
End of life usage |
| The chemical resistance of NEXTREMA® is more extensive than that of most other comparable materials. |
