Exploring the material

Find out which kind of glass-ceramic can make your next project become reality. Each with its own strengths, NEXTREMA® provides undeniable flexibility and potential.

NEXTREMA®
tinted

A homogeneously colored (dark-tinted) infrared glass-ceramic that is incredibly robust and temperature shock resistant. It is characterized by high mechanical stability.

Example applications
  • Attractive covers for indoor and outdoor radiant heaters
  • Glare-reducing covers for infrared heaters (e.g. in industrial drying processes)
  • Decorative element for applications in the fields of architecture, furniture and the house-hold appliance industry
NEXTREMA®
translucent bluegrey

The material type translucent bluegrey offers countless possibilities for engineers and designers in the IR range. This NEXTREMA® type boasts more than outstanding infrared wave transmission – and enabling a dead-front effect, too. I.e. when viewed from the top, none of the parts installed below are visible, yet the light still shines from below.

Example applications
  • Elegant cover plates for indoor and outdoor heaters
  • Decorative element for applications in the fields of architecture, furniture and the house-hold appliances
NEXTREMA®
opaque grey

The opaque grey material type is a top-quality glass-ceramic used in countless applications. It is the strongest heat-insulator out of all NEXTREMA® types. This is down to its low overall transmission in the IR spectrum. Opaque grey also boasts enormous temperature resistance.

Example applications
  • Inner lining of high-temperature cleanroom furnaces (e.g. in display manufacturing)
  • Easy-clean cover plates for magnetrons in microwave ovens
  • Decorative cover plates for dark radiator heating systems
NEXTREMA®
transparent

The glass-ceramic with the highest resistance to temperature shocks out of all six material types: it can withstand even drastic temperature differences of up to 820 °C.

Example applications
  • Cover plates for radiant heating elements in industrial processes
  • Inspection windows for high-temperature processes
  • Support plates for high-temperature processes
  • Substrates for transparent thin-layer heating elements
NEXTREMA®
translucent white

The material type translucent white is a high IR transmission glass-ceramic. This glass-ceramic possesses the widest IR transmission range (below 2,800 nm) of all NEXTREMA® types. Its chemical resistance is impressive too.

Example applications
  • Glare-reducing covers for radiant heaters in (non-) industrial processes
  • Elegant cover plates for indoor and outdoor heaters
  • Heat beds for 3D printers
NEXTREMA®
opaque white

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.

Example applications
  • Inner lining for high-temperature cleanroom furnaces
  • Easy-clean cover plates for magnetrons in microwave ovens
  • Decorative element for applications in the fields of architecture, furniture and the household appliance industry
  • Light diffusers for the lighting sector
