PCTFE, formerly called by its original trade name, KEL-F®, has higher tensile strength and lower deformation under load than other fluoropolymers. It has a lower glass transition temperature than other fluoropolymers. Like most or all other fluoropolymers it is inflammable. PCTFE really shines in cryogenic temperatures, as it retains its flexibility down to -200°F (-129®C) or more. It does not absorb visible light but is susceptible to degradation caused by exposure to radiation. PCTFE is resistant to oxidation and has a relatively low melting point. Like other fluoropolymers, it is frequently used in applications that require zero water absorption and good chemical resistance.
