Many technical properties of materials depend on the temperature. Examples include elasticity and hardness. Temperature resistance (also heat resistance) describes the ability of a material to maintain its relevant technical properties under high heat.
Materials or finished products with special temperature resistance therefore have a higher upper temperature limit.
Above this limit, their properties change to such an extent that they become unusable or destroyed.
#1 Definition of temperature resistance
Temperature resistance is the resistance of materials, semi-finished or finished products to the effects of heat.
The individual temperature resistance limit marks the upper temperature limit at which the temperature-dependent properties of the material change significantly. Solids may melt or ignite.
#2 Importance of temperature resistance
Temperature resistance is an important criterion for the selection of materials in sealing technology. Friction and hot media can lead to a high temperature input into the sealing elements.
O-rings with a pronounced temperature resistance retain their sealing properties for longer.
