Neat CF PEEK 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 PEEK grades based on tensile strength are  

The behaviour at low temperatures is good, 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, 80-85% of the original value.
