PES examples of tensile strength retention versus temperature C

For long-term heat ageing, property retention depends on the property and grades considered, notably the heat stabilizers used. Impact strength and elongation at break are especially heat-sensitive characteristics. 

Half-lives of specific PES grades based on tensile strength are  

At low temperatures, the behaviour can be reasonably good down to -100°C, depending on the grades and the mechanical constraints experienced. 

Generally, notched Izod impact strengths slowly decrease between room temperature and -40°C retaining, for example, 90% of the original value. 

Glass transition temperatures are high, roughly 185°C up to 200°C, and even 260°C for a special heat-resistant grade.
