Leveraging infrared heating technology

Improving performance and reducing costs are critical success factors for all kind of processes throughout mechanical engineering. NEXTREMA® is a versatile glass-ceramic material platform combining different technical properties to enable successful solutions in machineries and plant engineering i.e. for display equipment manufacturing or in infrared (IR) heating applications. The process inert material is the perfect match for inner lining, infrared heater cover, or carrier plates especially in high-temperature environments (for example inline or batch furnaces) where other materials such as plastic, conventional glass or metal show their limitations. Especially for IR heaters, the glass-ceramic material platform offers a broad range of options for different needs, such as protective heater cover against impacts or for more even heat distribution.

1 Applies to NEXTREMA® opaque white for 1 hour at 950°C homogenous heating. For inhomogeneous heating and other NEXTREMA® variants, the operating temperature may vary.
2 Applies to NEXTREMA® transparent. Tested by quenching a homogeneously heated NEXTREMA® transparent panel (820°C) with room temperature water (20°C). Values may differ for other NEXTREMA® variants.

A match for industrial applications

Especially in mechanical engineering, requirements become increasingly demanding, intervals become tighter, and processes need to be constantly optimized and refined. NEXTREMA® has proven its reliable performance in different application fields and use cases.

Heater cover

Due to its process inertness, its dedicated transmission and its near zero thermal expansion NEXTREMA® perfectly matches the requirements of an industrial infrared heater cover. No matter if you want to dry car paint, mold plastic containers, or dry food with IR heating – our glass-ceramic is the material of choice.

Carrier plates

When your products – for example displays or solar panels – run through a high-temperature process, NEXTREMA® is ideally suited for the use as a carrier plate: its near zero thermal expansion enables rapid heating and cooling while its high mechanical strength guarantees that the carried objects keep their shape.

Inner lining and insulation

Two types of NEXTREMA® show a very low transmission in the IR range – leading to good insulation in high temperature processes and saving you energy costs. At the same time our glass-ceramic is process inert, withstand temperatures up to 950°C¹ depending on the material type and is easy to clean.

Viewing window

One NEXTREMA® type perfectly suits an application as a viewing window. Not only because it’s transparent, but also due to its optional infrared reflective coating, that reflects radiation back into the chamber. Not to forget the material’s continuous heat resistance and its non-porous surface which makes it easy to clean.
