High performance glass ceramic. A true multitalent, NEXTREMA® demonstrates what makes glass ceramics a new and unique solution, particularly at high temperatures.  It is a high-tech material with many features. Particularly in high temperature environments, where other materials such as plastic, conventional glass or metal show their limits, NEXTREMA ® is your alternative. In engineering applications construction, your main interest are physical and chemical parameters, robustness under extreme temperature loads and high temperatures.
