These non-wetting, non-charring films have no electrical tracking and offer: Chemical compatibility, inertness, and solvent-resistance to nearly all chemicals. 030 - 0. At a high temperature around the crystalline melting point of the cable jacket material, sharp expansion and contraction occur in the jacket material[3]. In total, 580 uniaxial tensile tests were carried out. They are high-performance resins that can be processed at relatively high rates, compared with other fluorocarbon resins. Tefzel™ ETFE Fluoropolymer Film Table 2: Types and Gauges of Tefzel™ ETFE Fluoropolymer Film Gauge 50 100 200 500 Thickness, mil 0. As a result, this melt temperature measure-ment is not the most useful. Daikin ETFE is an alternating copolymer of ethylene and tetrafluoroethylene. ETFE has electrical properties and chemical resistance. Table 1: Types and Gauges of DuPont™ Tefzel® ETFE Fluoroplastic Film Gauge 50 100 200 500 Thickness, mil 0. 137 0. They are mechanically tough and offer an excellent balance of properties. 10. Figure 1 also shows that ETFE is a highly crystalline polymer, crystallinity level based on. 5 25 50 125 Approx. Because the latter monomer mainly exists as its tautomer acetaldehyde, the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis. DERATING FACTORS FOR BUNDLED CONDUCTORS Bundle # Deratinq Factors ( x Amps ) 2-5 0. The modulus and yield strength increase with increasing dose, and these phenomena are clearly distinguished above the melting temperature of ETFE (533 K). Firstly, the low melting point of ETFE means that in temperatures above 200°C, the film will. Temperature [°C] C 64 D C 95 A C 85 A Fig. 3 g/cm 3 and melt viscosity in the range of 1-10 GPa per second.
