The polymer maintains high impact strength in cryogenic applications. 2-0. ETFE (ethylene-tetrafl uoroethylene) is a partially fl uorinated copolymer that is oc-casionally modifi ed by a third monomer to attain certain properties. Offers high melt flow rate, high heat resistance, excellent chemical resistance, excellent physical toughness, low smoke & flame characteristics, good dielectric properties, excellent resistance to weather & aging, and non-stick characteristics. area factor, m2/kg 40 20 10 4 Availability Type LZ - ETFE, general-purpose X X X X Type CLZ - ETFE, one side cementable — X X Xstill maintains a service temperature of 150 °C (302 °F). Not only can ETFE tubing resist melting in extreme heat, it can do so for a significant duration of time. 7 1. Lower T g (glass transition temperature) occurs at –15°C to –20°C and upper T g is in the 40°C to 50°C range. 0: Btu/lb/deg F kJ/Kg/deg K: Heat Distortion Temperature, 66 lb/sq. ETFE ethylene-tetrafluoroethylene (was E/TFE in ISO) EVAC ethylene-vinyl acetate EVAL See EVOH EVOH ethylene-vinyl alcohol (was EVAL in ISO).

ETFE - Ethylene Tetrafluoroethylene: 140: 155: EVA - Ethylene Vinyl Acetate: 45: 70: EVOH - Ethylene Vinyl Alcohol: 80: 100: FEP - Fluorinated Ethylene. The loss modulus for ETFE-SA is clearly higher at the rubber plateau area, which is a temperature range approximately 170–230 ° C. Wang J, Zhang Y. Table2. It is worth mentioning that the region, in which the mechanical property deceases beyond the softening temperature (i. PFA, or Perfluoralkoxy, is a high temperature version of FEP. Compared with other grades of Tefzel™, it has a higher flow rate. 24: 0. The dissipation factor of ETFE, measured from -150°C to 210°C, shows two peaks at -80°C and 92°C, which are associated with molecular relaxations. 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). AGC Chemicals Americas, Inc. PTFE is used as an inner coating material in non-stick cookware. As a. 2 – 1. For rotational molding, Tefzel™ ETFE HT-2195 powder is placed inside a hollow metal structure that is slowly rotated biaxially and heated above the melting point of the powder around 257 °C (495°F). ETFE is a fluoroplastic (fluorine-based thermoplastic). Other characteristics of Tefzel™ ETFE resins include: Low wear factor (1/10 of reinforced nylon) High-impact strength and dimensional stability; Heat resistance with a rating for temperatures up to 150 °C (302 °F) based on the 20,000-hour criterion and good creep resistance; Low flammability; Specific gravity of 1. Ethylene tetrafluoroethylene (ETFE) is a polymer with a high melting temperature threshold, excellent radiation, electrical and chemical resistance properties. The melt flow index is the amount measured in grams that exits the die in 10 minutes. Commercial ETFE is a copolymer of ethylene and tetrafluoroethylene. The operating temperature of Virgin PTFE (PTFE with no fillers) ranges from -75⁰C to +260⁰C. ETFE is a melt processable copolymer of ethylene and tetrafluoroethylene. followed by an annealing treatment at approximately 20 °C below the melting temperature. Stainless steel and Hastelloy alloy differences. The mechanical properties of ETFE are superior to those of PTFE and FEP. Department of Energy Office of Scientific and Technical Information.
