At 500 °F (260 °C), PFA has a higher service temperature than FEP and maintains its mechanical integrity in extreme temperatures even when exposed to caustic chemicals. Heat Deflection Temperature At 1. 17 2 . Tefzel® ETFE has excellent chemical resistance & can be applied as thick as PFA but is the tougher. Expand. Whitford Corporation. T PTFE Outstanding resistance to corrosives, -95°F to 500°F temperature rating. ETFE HT-2181 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. This document is also possibly applicable to thermoplastics for which the rheological behaviour is affected during the measurement by phenomena. still maintains a service temperature of 150 °C (302 °F). Most people commonly utilise PTFE by using a commonly seen trademark: Teflon, which is a PTFE coating for non-stick household items. Cable insulation is used to provide electrical separation between conductors of a cable. To safely design ETFE foil structures, their mechan-ical behaviour has to be fundamentally. The distilled 2a was crystallized from hexane and had a melting point of 75–77 °C. 455 MPa), 4 mm thick: 293 145: deg F deg C: D 648: Service Temperature: to 302 to 150: deg F deg C. ETFE has lower low-temperature brittleness than Halar ECTFE. area factor, m2/kg 40 20 10 4 Availability Type LZ—ETFE, general-purpose X X X X Type CLZ—ETFE, one side. g. 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. to diameter (24/1 up to 30/1 and beyond) and heaters should have the capacity to heat material to approximately 340°C. ETFE has approximately 95% light transmittance, but does not offer the clear visibility/transparency of glass (Robinson, 2005). 7 Higher flow ETFE grade Tefzel® ETFE ETFE HT2195 150 — — 20 253 — — — 1. PCTFE or CTFE (originally known as Kel-F*) has many of the properties similar to other fluoropolymers such as PTFE, FEP or PFA, but is mechanically superior in rigidity (does not deform easily), and has very low gas permeability . 6 0. Melt-. ETFE, or ethylene tetrafluoroethylene, consists of carbon, fluorine and hydrogen, has a higher tensile strength than PTFE, though PTFE will stretch before breaking. Wang J, Zhang Y. 305°CTin Coating = 150°C Max. 287 – 0. Features include chemical and abrasion resistance. The melting temperature of ETFE is 270-300 ℃, but the applicant finds that the composite material has better performance by selectively controlling the melting temperature of ETFE to be not higher than 220 ℃, particularly controlling the. The 3M TC hot melt stick size is a 5/8” X 2” glue stick meant for use with the 3M Polygun TC or Polygun LT (depending on temperature, but we'll get into that later). Properly processed products made from neat Tefzel™ ETFE HT-2184 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. area factor, ft2/lb 200 100 50 20 Approx. It can typically handle temperatures from approximately -76°C to +150°C (-105°F to +302°F), providing better performance in both high and low-temperature environments. In addition to enjoying the unique properties of fluoropolymers, PFA differentiates itself by. ETFE (Tefzel®) Highest room temperature strength and stiffness of the fluoropolymers make it an excellent choice for.
