PCTFE examples of swelling for short immersion times

Fire resistance is naturally good but PCTFE releases corrosive and toxic fumes in the event of fire. Oxygen indices are 95 or more and UL94 rating is VO. 

PCTFEs are good insulators even in wet environments, with high resistivities. 

Welding is difficult but possible for certain grades using thermal processes. 

All precautions must be taken concerning health and safety according to the local laws and regulations. 

being a copolymer of monochlorotrifluoroethylene and ethylene, has a lower halogen content than PCTFE, and the outstanding performances are of a somewhat lower level. On the other hand, it offers easier processing and the mechanical characteristics are better. Crystallinity is generally about 50%.
