Heat resistant, chemically resistant glass-ceramic: SCHOTT NEXTREMA® opaque white (724-8)

The material type opaque white is a glass-ceramic that stands out in particular due to its temperature resistance. The opaque, durable glass-ceramic possesses excellent heat resistance: it can withstand up to 950 °C. This makes the glass-ceramic a reliable partner in high-temperature and microwave applications. What’s more, it is particularly effective in applications where low radiation is to be ensured across a wide wavelength range in visible and infrared spectrum. Chemical resistance to acids and bases according to DIN 12116, ISO 695 und DIN ISO 719 allows the special glass to withstand even the most demanding conditions. The premium homogeneously colored white material can be used to realize countless esthetic ideas in the fields of architecture and design. Its special surface is opaque, non-porous and adds a dazzling, sophisticated touch to all sorts of designs.
