Our engineers and designers frequently ask us this question when looking for the exact temperature at which silicone rubber will begin to degrade in applications. What temperature is reliable ?
As a general rule, our experts cannot provide a definitive answer without discussing in further detail the environment. In which the silicone will be located and the temperature(s) to which it will be exposed.
In contrast to most High Temp Silicone Sheet, High Temperature Resistant Material is able to withstand extreme temperatures below -60°C without deforming. What temperature is reliable, Silicone can only withstand certain temperatures due to one aspect, namely, TIME.
In terms of rubber materials, the duration of exposure to extreme temperatures determines their lifespan and performance, which is a crucial consideration whenever rubber is specified in applications.
How hot can silicone get before it melts?
If you notice, silicone doesn’t melt just because of the temperature!
For example, if silicone were heat to 150°C for an extended period of time. Very little change would occur in the silicone. As the silicone is heat to a temperature of over 300°C. Then the material becomes harder and less flexible very quickly.
At a temperature of 200°C the silicone slowly becomes harder and less flexible over time. Although the temperatures were extreme, the material did not melt.
