By Steven McFadyen on May 15th, 2012. Pure ETFE is colorless and can be processed into transparent ETFE film with light transmittance of up to 95%. Capabilities. 003 for ETFE-0 membrane and F/C of 0. % of Zonyl®. PTFE has a slightly higher heat resistance but lacks when compared with the flow, creep resistance, and thermal stability. Stable mechanical electrical properties are maintained over a wide range of temperatures, -200 - +180°C. A detailed description of plastic melting and molding temperature ranges, inclusive of the recommended temperature values for all plastics. area factor, m2/kg 40 20 10 4 Availability Type LZ—ETFE, general-purpose X X X X Type CLZ—ETFE, one side. 008 11 255–280 40 300 1000 1. Electrical properties. ETFE (ethylene-tetrafl uoroethylene) is a partially fl uorinated copolymer that is oc-casionally modifi ed by a third monomer to attain certain properties. The T d was defined as the point at which the mass loss was 5%. 45MPa C Heat-deflection temperature - 1. [ 12 ],. They are mechanically tough and offer an excellent balance of properties. Melting point: −142. The. As shown in Figure 4, the T m of PTFE fiber was. At a high temperature around the crystalline melting point of the cable jacket material, sharp expansion and contraction occur in the jacket material[3]. UL1581. The melt point of ETFE is about 242 °C, and crystallization point 259 °C. • Low permeability to liquids, gases, moisture, and organic vapors. 7-fold excess of that of the fluorine atoms in ETFE) at 320 °C, the yields of F – and. PTFE, FEP, ECTFE, EFEP, ETFE, PCTFE, PFA, PVDF: Typical Thermoplastic Materials (Contact us for additional options). It is recommended that for extrusion processing of Tefzel™ The properties of Tefzel ETFE 750, a melt temperature of 332 °C (630 °F) be maintained and, in any case, should not exceed 335 °C (635 °F). Vapor Temperature, °C g/100 sq in. 2012;69:375–88. Fluorinated Ethylene Propylene (FEP) FEP is a copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP), first produced by DuPont in 1956 (Teflon™ FEP) to reduce PTFE’s high crystallinity and melt viscosity. area factor, m2/kg 40 20 10 4 Availability Type LZ - ETFE, general-purpose X X X X Type CLZ - ETFE, one side cementable — X X Xstill maintains a service temperature of 150 °C (302 °F). Specifically, when ETFE (30 mg) was treated for 6 h with aqueous KMnO 4 (52. The area under the peak is the heat of fusion. However, ETFE is Table 1: Types and Gauges of DuPont™ Tefzel® ETFE Fluoroplastic Film Gauge 50 100 200 500 Thickness, mil 0. Thus, standard temperature resistance is the same, ETFE is safer at higher temperature fluctuations. It is partially crystalline (50–55%) and melts at 240.
