Thermal properties
Coefficient of mean linear thermal expansion
α(20, 700°C) (0 ± 0,5) x 10-6 /K
Resistance to thermal gradients (RTG)
The RTG value is a measure of how well a material can resist temperature differences on a restricted area, e.g. the temperature difference between the hot area in the center of a panel and the cold edge area (room temperature).
No breakage caused by thermal stress occurs at a maximum temperature of Tmax ≤ 700°C
Resistance to thermal shock (RTS)
The RTS value is a measure of the panel‘s ability to withstand a sudden thermal shock.
No breakage caused by thermal stress occurs at a maximum temperature of Tmax ≤ 700°C

Temperature/Time Loading
The temperature/time loading limits determine the permissible temperature for set usage times at which no breakage caused by thermal stress occurs.

Remarks:
The temperature values refer to the hottest points on the outside pane. (Tmax). It must be ensured that these temperature/time loading limits are not exceeded.
