Ethylene tetrafluoroethylene (ETFE) is one of the most promising polymer that can be used in building textiles due to its high melting temperature, excellent radiation. In the event of a fire ETFE does not promote the spread of flames because it self-extinguishes and does not generate any. It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. As a result, this melt temperature measure-ment is not the most useful. PCTFE is stiffer than PTFE, which means it lacks some of the softness of PTFE when it comes to sealing, but that it also holds its dimensions more easily. Nonetheless, PTFE is better suited for high-temperature applications. Commercial ETFE is a copolymer of ethylene and tetrafluoroethylene. (1) Light weight and high strength -- ETFE density is 1.

These low melting fluoropolymer resins are processable by conventional extrusion and injection molding techniques. com Max. ETFE specimens were irradiated at liquid nitrogen (77 K) within 20 MGy with a dose rate of 29. The thermal scanning procedure, including melt and crystallization, follows below: (1) melt behavior, staying 5 min at -50 C then heating (10 C/min) to 350 C; (2) crystallization behavior, ETFE. 1007/s00289-012. 009 14 220–240 40 300 800 1. They have lower chemical resistance and thermal stability than perfluorinated polymers. area factor, ft2/lb 200 100 50 20 Approx. A detailed description of plastic melting and molding temperature ranges, inclusive of the recommended temperature values for all plastics. 209: Btu·in/h·ft2·°F W/m·K: Heat Distortion Temperature, 66 lb/sq. 006 7 220–255 38 300 645 1. 49°C and 480°C. @Temperature 300 - 330 °C: 1. 5 °F; 130. ETFE : 10126: 32 - 4/0: 600: 150°C: 0. The melting point ranges from 220 to 280 °C. 1 MPa of the same sample as used in the SAXS measurement was determined. Thermal Expansion -in/(in °F) ASTM D696 4x105Abstract: With the first use of ETFE foils in building structures in the 1980s at the Burgers’ Zoo in Arnhem, Netherlands, the implementation of ETFE foils in roof and façade systems in large-span structures has become steadily more prominent. ETFE. Figure 1. 5 25 50 125 Approx. Excellent chemical resistance; Outstanding physical toughness: Fluon ETFE has better physical properties than most other fluoropolymers. This type of plastic material does not have a sharp melting point, but softens to a melt over a broad range of temperature. apart from the tests at testing temperature T 0 for the ETFE foil from producer III with only three tests per test combination. Tefzel ™ ETFE 207 and the other Tefzel fluoroplastics are melt processible, modified copolymers of ethylene and tetrafluoroethylene. Glass Transition Temperature. The outer layer of ETFE foil is printed with a silver ink to create a "frit" that helps reduce the heat of the sun on the roof surface and deflect the sun, while the inner layer of air helps. 57 A, b = 11. It is worth mentioning that the region, in which the mechanical property deceases beyond the softening temperature (i. PFA – Perfluoroalkoxy (vinyl ether) - TYPICAL PROPERTIES. Used in electrical components such as sleeving, coil forms, sockets, connectors & switches, lab ware like tubing, valves, containers &. area factor, ft2/lb 200 100 50 20 Approx. 7 16-30 0. Oxygen plasma exposure. 49°C and 480°C, which were 52. Fig. 1. PFA, or Perfluoralkoxy, is a high temperature version of FEP. Description: Fluon® ETFE is a melt-processable copolymer of tetrafluoroethylene and ethylene. An example of a suitable resin for rotational molding is Tefzel ® HT-2190 ETFE [22]. Irradiation temperature was covered from 77 to 573 K (over the melting temperature). With a marginally higher tensile strength, PCTFE rates higher than PTFE on this metric. and rod dia. ETFE is also used in the production of chemical pumps, valves, and gaskets, where its high strength and flexibility are. 76 Hexane 35 0. 04 Red Fuming Nitric Acid 25 7. 5 mm (0. The individually isolated ETFE iodide components 2a and 2b were also solids at room temperature. MIL-W-22759 has since been replaced with the classification SAE AS22759 but is still commonly. [2] Fluorinated ethylene propylene was invented by DuPont and is sold under the. To safely design ETFE foil structures, their mechan-ical behaviour has to be fundamentally. ETFE and PTFE can resist temperatures much over their melting points without suffering ill effects. 5 1 2 5 Thickness, µm 12. During recent years, there has been some. ETFE, Description: Fluon® ETFE is a melt-processable copolymer of tetrafluoroethylene and ethylene. ETFE film, is now increasingly being applied to the solar industry, it is very suitable for the surface of the solar cell material.
