Mechanical properties (at room temperature)

High intrinsic mechanical strength even under high temperatures
NEXTREMA® shows attractive mechanical strength without the need for additional toughening processes. Even under high temperatures NEXTREMA® shows exceptional mechanical stability, making it the material of choice where high mechanical strength and temperature resistance are needed.

Bending strength
(DIN EN 1288, Part 5, R45)  
Impact resistance      The impact resistance of NEXTREMA® depends on the kind of installation, size,
thickness and geometry of the panel, type of impact and especially on drilled
holes and their position in the material.

Therefore, information regarding impact resistance can only be given with
knowledge of the respective and defined application (especially in combination
with the technical standards regarding impact resistance that have to be met for
some applications). The quality of the grinding profile has an important influence
according to the impact resistance.
