ETFE, Description: Fluon® ETFE is a melt-processable copolymer of tetrafluoroethylene and ethylene. Other factors such as the time of exposure to elevated temperature, the rate of temperature increase, and the part geometry all affect the performance. It is generally composed of at least 20 wt. ETFE; Cylinder Temperature, °. Melting point: −142. Note 1 to entry: Plastics which, when containing absorbed water and heated above their glass transition temperatures (for amorphous plastics) or melting point (for semi-crystalline plastics), undergo hydrolysis resulting in a reduction in molar mass and consequently a reduction in melt viscosity and an increase in MFR and MVR. Tefzel® has a broad continuous use temperature range from –150° to 300°F (–100° to 150°C). ABS/Polycarbonate ALLOY. Green.
