Tefzel™  ETFE HT-2170 resin combines the chemical and  high-temperature resistance of Tefzel™  with antistatic levels  of electrical conductivity. Tefzel™  ETFE HT-2170 and the  other Tefzel™  fluoroplastics are melt processible, modified  copolymers of ethylene and tetrafluoroethylene. They are  high-performance resins that can be processed at relatively  high rates, compared to other fluorocarbon resins. They  are mechanically tough and offer an excellent balance of  properties. 

Tefzel™  ETFE HT-2170 can perform successfully in  applications where other thermoplastics are lacking in  mechanical toughness, broad thermal capability, ability  to meet difficult environmental conditions, or limited by  fabricating problems. 

Properly processed products made from neat Tefzel™ ETFE HT-2170 are inert to most solvents and chemicals,  hydrolytically stable, and weather-resistant. The  recommended upper service temperature is 150 °C (302  °F); useful properties are retained at cryogenic ranges.  Mechanical properties include outstanding impact strength,  cut-through, and abrasion resistance. The main advantage  of Tefzel™  ETFE HT-2170 is that it has improved stress  crack resistance and flexibility when compared to other  static-dissipating Tefzel™  ETFE resins. To gain stress crack  resistance, some physical strength has been sacrificed (see  Table 1 for details).
