It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. AGC Fluon® C-88AXP ETFE. Fluon ® LM-ETFE Resins. In addition to enjoying the unique properties of fluoropolymers, PFA differentiates itself by. 45MPa C Heat-deflection temperature - 1. ETFE can operate in wide temperature ranges, has low water absorption, and performs well with ETO (ethylene oxide), autoclave, and gamma sterilizations. ETFE specimens were irradiated at liquid nitrogen (77 K) within 20 MGy with a dose rate of 29. Table 1: Types and Gauges of DuPont™ Tefzel® ETFE Fluoroplastic Film Gauge 50 100 200 500 Thickness, mil 0. Chemically resistant: The exceptions include molten alkali metals, gaseous fluorine at high temperatures and pressures, and a few organic halogenated compounds such as chlorine trifluoride (ClF 3) and oxygen difluoride (OF 2). 2% between 2021 and 2026ETFE is a semi-crystalline, melt processable thermoplastic that is essentially a 1:1 alternating copolymer of ethylene and tetrafluoroethylene. Good outgassing characteristics. 8MPa C Lower working temperature C Specific heat J K-1 kg-1 Thermal conductivity W m K-1 Upper working temperature C Polyimide PI 30-60 - 360 -270 1090 0. The modification of these phases makes it possible. 8 MPa (264 psi) load, and melting point values for some filled and unfilled polymers. As seen in the table below, Nylon 11 has lower values of density, flexural and Young's modulus, water absorption, as well as melting and glass transition temperatures. 190-270. Because its melt temperature is only a few degrees shy of its degradation temperature, it cannot be melt-processed. residual with increasing temperature, at which point the composite has reached to the melting temperature, Tm. * View additional table for data – click material name. The modulus and yield strength increase with increasing dose, and these phenomena are clearly distinguished above the melting temperature of ETFE (533 K). It has a high purity with service temperatures up to 150°C. has better mechanical properties at higher temperatures. ETFE is difficult to burn because it requires air with a higher oxygen concentration. 10. 46 J/g. Excellent resistance to extremes of temperature, ETFE has a working temperature range of −200°C to 150°C. cross-linked ETFE polymer. These behaviors have been interpreted successfully on the basis of the degree of alternation of E and TFE monomeric. Thus, they slow down the spre ad of fire and. ETFE has a broad operating temperature range from as low as –100 °C to 150 °C. The unit cell is orthorhombic with the dimensions: a = 8.
