Chemical information

Chemical formula: (C2F4) n .
CAS — 9002-84-0.


Polytef has numerous industrial applications. As ‘Teflon’ it is used on ‘non-stick’ cooking utensils. A paste of polytef has been used for a variety of purposes including the treatment of aphonia, for replacement grafts in vascular surgery, and in the correction of some forms of urinary incontinence. The main concern with these procedures is migration of polytef particles. It has also been applied to the skin as a barrier paste with perfluoroalkylpolyether to reduce exposure to chemical warfare agents.

Adverse effects.

Brain injury in a child was possibly associated with migration of polytef particles from a periureteral injection performed 1 year earlier.1 Three cases of polytef adenopathy and one case of giant granuloma have been reported2 in children who had previously undergone subureteral polytef injection for the treatment of vesicoureteral reflux.
