However, the high temperature limit for FEP is lower than PTFE, approximately 200°C instead of 260°C. Consequently, mechanical, dielectric and other properties of the product made from ETFE will be affected and toxic chemicals will be released when ETFE degrades at elevated temperatures [18]. Its dimensional stability makes it attractive for use as a component of a structural part where the high. The temperature range for process annealing ranges from 260 °C (500 °F) to 760 °C (1400 °F. PTFE can reach a maximum temperature of 327c whereas ETFE can reach a maximum temperature of. The wider temperature range allows for improved processability, flexibility and strength. The melting temperature depends on the sur-face curvature and decreases as size decreases. switches.
