ETFE has lower low-temperature brittleness than Halar ECTFE. Tefzel ™ ETFE 207 and the other Tefzel fluoroplastics are melt processible, modified copolymers of ethylene and tetrafluoroethylene. ETFE has approximately 95% light transmittance, but does not offer the clear visibility/transparency of glass (Robinson, 2005). (1) Light weight and high strength -- ETFE density is 1. V0. Impurities may include various chloro-fluoro compounds (ECETOC, 2003). 225 to 275 °C. 92% after 1. They have lower chemical resistance and thermal stability than perfluorinated polymers. Polym Bull. They are mechanically tough andEthylene tetrafluoroethylene (ETFE): ETFE exhibits excellent corrosion resistance, a high melting temperature, and superior resistance to chemicals, electrical current, and high-energy radiation. More difficult to work with than PTFE Teflon. 1 to 30 µm, a heat resistant resin, a dispersion medium, and a solvent for dissolving the heat resistant resin. 287 – 0. 63 mm 3 /s. Calculate the change in length, volume or density of a body with an increase in temperature. The melting point (T m), crystallization temperature (T c) and the decomposition temperature (T d) were noted on the DSC and TG curves. Melting Temperature Volume Resistivity Dissipation Factor Food Grade UL 94Ethylene tetrafluoroethylene (ETFE) is a fluorine -based plastic. Powder flow and distribution are critical because the high melt viscosity of Tefzel ® limits the lateral flow of melted resin. Increased Melting Point: Upper Use Temperatures similar to PTFE . 0 lb, Temperature 567 °F: ASTM. During the historical development of cables, numerous types of insulation have been employed. 77g/cm3, the weight of ETFE thin film per unit area is very light, only 1% of the glass mass of the same area, which can greatly reduce.
