The melting point of ETFE, 500 °F (260 °C), is higher than ECTFE, 473 °F (245 °C), ETFE thus provides a higher margin of safety in the event of an accident (for example, a “runaway” chemical reaction that could develop temperatures much higher than normal). Oshima et al. Specific temperature ratings vary with equipment design, thus it is important to consult with component manufacturers for in-use service recommendations. When both hold-up time is long and temperature is high, the rear zone should be set to a lower temperature than the front zone to minimize polymer degradation.

Commercial ethylene–chlorotrifluoroethylene (ECTFE) copolymer is an alternating polymer with 1:1 ratio of comonomers. 1). Green. ETFE Thermal Advantages: HigherMeltingPoint. The polymer chain has alternating CH 2 and CF 2 groups. A cooling step then causes the. Polym Bull. These materials are used as insulation in slants within M22759 military wire. These behaviors have been interpreted successfully on the basis of the degree of alternation of E and TFE monomeric. ETFE specimens were irradiated at liquid nitrogen (77 K) within 20 MGy with a dose rate of 29. 19 @23C The melting (T m) and glass transition (T g) temperatures of a series of ethylene (E)–tetrafluoroethylene (TFE) copolymer (ETFE) have been found to show unique dependence on the TFE content with the minimal and maximal points. The latter consisted of aluminum polyphosphate (AP) having a flow temperature near to that of ETFE to facilitate melt-mixing by extrusion, and rigid fillers of. Fluon® ETFE C-55AXP is a melt-processable copolymer of tetrafluoroethylene and ethylene that offers a unique combination of. Its resistance to corrosive chemicals and high temperatures make it an ideal material for these applications. 238: Btu/hr-. 4. 8MPa C Lower working temperature C Specific heat J K-1 kg-1 Thermal conductivity W m K-1 Upper working temperature C Polyimide PI 30-60 - 360 -270 1090 0. 24: 0. With decades of combined experience, our products can fit your needs in a variety of applications. This study mainly focused on the thermal stability of PVDF/ETFE blends. The great thing about XYLAN coatings is that they are available in virtually any color and can actually be custom matched to your pantone or RAL color standard requirements. ETFE has a melting point of approximately 260°C.
