NEXTREMA® Translucent White (724-5) Sheet
Description
NEXTREMA® is a unique glass-ceramic material platform. This material combines the glossy appearance of glass with exceptional thermal, chemical, optical and mechanical properties like an attractive bending strength of 100 - 165 MPa for materials with a thickness of around 4 mm. With a thermal resistance of up to 950 °C, depending on the material type, combined with a thermal shock resistance of 600 - 820 °C, it ensures a reliable material performance even under extreme temperature conditions. Our six unique glass-ceramic types combined with the wide range of sizes and thicknesses varying from 2 mm to 6 mm (> 6 mm on request) will open up new possibilities in product design and performance. The unique transmission spectra provide new ideas for combining innovative infrared heating functionalities with attractive lighting effects. The versatility of this material will surely impress you.
