Polyfluortrifluorethylen (PCTFE)
Proper name: PCTFE (Polychlorotrifluoroethene)
 Trade names: Neoflon PCTFE (Daikin), Voltalef (Atofina), Kel-F 
 Density g/cm³: 2.1 to 2.13 
 Description: PCTFE is a semi-crystalline, thermoplastic fluoroplastic. It is characterised by a good strength and hardness - it is weather-resistant and can be used with food. Areas of application PCTFE is especially used in apparatus engineering due to its unique temperature characteristics. 
 Application examples: 
 Valve technology: springs, check valves, application in ultra-clean rooms 
 Medical engineering: gas-tight special packaging films 
 Filling industry: pumps, seals for liquids foods (dairies) 
 Laboratory technology: high purity gas valves, seals, fittings, hoses, membranes, crucibles 
 Electrical engineering: sealing-rings 
 Flammability: non-flammable 
 Temperature resistance: upper service temperature + 180 °C lower service temperature - 230 °C
