The general ‘rule of thumb’ for silicone oil is that it expands (or contracts) by approximately 10% per 100°C (1% per 10°C). Note that this relationship can vary depending on the temperature and the particular thermal fluid used.
What happens to silicone at high temperatures?
While most plastics will begin to melt at high temperatures, silicone does not have a melting point and remains solid until combustion occurs. At high temperatures (200-450oC), silicone rubber will slowly lose its mechanical properties over time, becoming brittle.
