ECTFE examples of tensile stress TS modulus retentions versus temperature C

At low temperatures, the behaviour can be reasonably good down to -76°C and even -200°C, depending on the grade and the mechanical constraints undergone. 

At -40°C, for a given ECTFE grade, notched Izod impact strength is about 160 J/m. These results relate to some grades only and cannot be generalized. 

The mechanical properties at room temperature are generally fair with a rather low modulus and an excellent impact strength, but performances decrease as the temperature rises. 

Alterations by moisture exposure are very weak but shrinkage and coefficients of thermal expansion are high creep resistance is low.
