Oxygen plasma exposure. Temperature Range: ETFE has a broad temperature operating range, similar to ECTFE. ETFE polymers are melt processible. They are mechanically tough and ETFE. 013, respectively. The melt point of ETFE is about 242 °C, and crystallization point 259 °C. Four planar zigzag chains are packed in the unit cell. The heat deflection temperature (HDT) is a measure of the polymer’s resistance to distortion under a given load at an elevated temperature. in (0. Ethylene-tetrafluoroethylene - Chemical Compound (ETFE) ETFE is a fluorine based plastic, and could be described as a tough high strength version of PTFE. The recommended upper service temperature is 155 °C (311 °F); useful properties are retained at cryogenic ranges. Description: Fluon® ETFE is a melt-processable copolymer of tetrafluoroethylene and ethylene. 1. ETFE has an approximate tensile strength of 42 MPa (6100 psi), with a working temperature range of 89 K to 423 K ( −185 °C to +150 °C or −300 °F to +300 °F ). [2] Fluorinated ethylene propylene was invented by DuPont and is sold under the. It was Fluorinated ethylene propylene ( FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene. 74 1. Melting Point; Maximum Service Temperature, Air; Deflection Temperature at 0. It is the best known non-stick material with a coefficient friction comparable to wet ice on wet ice. 5 25 50 125 Approx. Such cookware is also easy to wash. Wang J, Zhang Y. In particular, PVDF and ETFE are isomers; PVDF has a higher thermal decomposition temperature than ETFE. It is also highly durable, with a lifespan of up to 50 years, and can be recycled at the end of its useful life. 4 D1894 KEY FEATURES ETHYLENE TETRAFLUOROETHYLENE (ETFE) TYPICAL PROPERTY VALUES DESCRIPTION Filler. 5-mm (0. The melting point ranges from 220 to 280 °C. @Temperature 300 - 330 °C 1. to diameter (24/1 up to 30/1 and beyond) and heaters should have the capacity to heat material to approximately 340°C. Tefzel® ETFE ETFE HT2188 150 2. We have been doing this for companies since 1947. The wider temperature range allows for improved processability, flexibility and strength. V. At the melting point the solid and liquid phase exist in equilibrium. Methods to Process ETFE Processing temperature: 290 to 340°C Drying is recommended but not necessary Injection Molding: A mold temperature of 65-150°C is recommended Extrusion: Extruder barrels should be long, relative to diameter, to provide residence time for heating the resin to. Characteristics. ETFE: ECTFE: Maximum Service Temp. It has the highest level of mechanical toughness in the fluoroplastic family, with superior creep and outstanding corrosion resistance over a wide temperature range up to 150°C (302°F). Tefzel™ ETFE (ethylenetetrafluoroethylene) is a melt processable fluoroplastic resin. S. This unique polymer coating prevents food from sticking in the pans during the cooking process. The Texlon ® ETFE system is the transparent roofing and façade solution that covers unique spaces and can be tailored to the exact needs of the project. It can typically withstand temperatures from approximately -200°C to +150°C (-328°F to +302°F), providing excellent performance in both high and low-temperature applications. 040 cm/cm 0. Density: It has a density in the range of 2. UL-758. •Generally occurs at high temperature (thermal creep), but can also happen at room temperature in certain materials (e. Following are some of theSection snippets Materials.
