Table 1 showsETFE also has higher heat resistance, with a melting point of 327°C, which is 60°C higher than PTFE. 16 0. 137 0. Figures 1 and 2 depict the relative heat flux curves of Halar® 901 and Halar® 902, respectively, as a function of temperature during heating, than 40% increase) in melt flow number could reduce the stress crack resistance of the insulated or jacketed cable. The activation energy of thermal degradation (E d) of ETFE was 66 kJ/mol, while the PVDF/ETFE (10/90 wt%). ETFE. Tefzel™ ETFE Conductive Fluoroplastic Version 3. It is also used as a monomer in the. It provides the superior properties typical of fluoropolymer resins, such as excellent retention of properties after service, chemical inertness, and mechanical toughness. 4 Technical products and impurities Industrial-grade tetrafluoroethylene gener-ally has a purity of > 99. 01 MPa at a temperature of 270 ° C corresponds with the melting of ETFE. ETFE has approximately 95% light transmittance, but does not offer the clear visibility/transparency of glass (Robinson, 2005). ETFE has a relatively high melting temperature, excellent chemical, electrical and high-energy. 2-0. 1-in) pellets. 5 K. Oshima et al. The XL-ETFE typically has a higher melting temperature than the straight material. Teflon can be used in a a variety of applications having a combination of mechanical, electrical, chemical, temperature and anti-friction properties that are unmatched. 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. 209: Btu·in/h·ft2·°F W/m·K: Heat Distortion Temperature, 66 lb/sq. There are 14 material properties with values for both materials. 2. ETFE can branded as Tefzel™, made by DuPont™/Chemours™. ECTFE’s chemical structure gives it very low permeation to. Silver Coating = 200°C Max. Maximum Temperature: Mechanical, °C: 160: 260 to 270: Melting Onset (Solidus), °C: 260: 330 to 340: Thermal Conductivity, W/m-K: 0. 7 mM; the molar amount was 1. release properties and flexibility over a broad continuous use temperature range. Fig. The area under the peak is the heat of fusion. This document is also possibly applicable to thermoplastics for which the rheological behaviour is affected during the measurement by phenomena. Electrical properties. Elongation. Compared to glass, ETFE film.
