The loss modulus for ETFE-SA is clearly higher at the rubber plateau area, which is a temperature range approximately 170–230 ° C. It has strong impact resistance and a Young's modulus in the range of 1700 MPa, allowing for self-standing items and pressure piping systems. 1). Tefzel® ETFE ETFE 750 200 2. 4 Summary of. Tefzel™ ETFE HT-2185 and the other Tefzel™ fluoroplastics are melt processible, modified copolymers of ethylene and tetrafluoroethylene. 305°C ETFE has an approximate tensile strength of 42 MPa (6100 psi), with a working temperature range of 89 K to 423 K ( −185 °C to +150 °C or −300 °F to +300 °F ). 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 XMaterials Overview. ETFE was designed to have high corrosion resistance and strength over a wide temperature range. Standard Number. 16 0. PCTFE or CTFE (originally known as Kel-F*) has many of the properties similar to other fluoropolymers such as PTFE, FEP or PFA, but is mechanically superior in rigidity (does not deform easily), and has very low gas permeability .

As a result, this melt temperature measure-ment is not the most useful. The crystal structure for an ethylene-tetrafluoroethylene (ETFE) alternating copolymer film containing highly ordered crystal regions was determined. 25:. 040 in/inBoth ETFE and PFA are thermoplastics. 10. 2. A low thermal conductivity of FRP materials is demonstrated notwithstanding such unfavourable behaviour under fire [3 3]. An artificial weathering test (comparable to 30 years’ exposure) produced no filtering and almost no signs. The recommended upper service temperature is 155 °C (311 °F); useful properties are retained at cryogenic ranges. Density: It has a density in the range of 2. At the melting point the solid and liquid phase exist in equilibrium. A detailed description of plastic melting and molding temperature ranges, inclusive of the recommended temperature values for all plastics. 1. Due to Irradiation The ETFE specimens were irradiated by 7-rays or electron beam (EB) under oxygen-free atmosphere. 4. Ethylene-tetrafluoroethylene - Chemical Compound (ETFE) ETFE is a fluorine based plastic, and could be described as a tough high strength version of PTFE. Both ETFE and XL-ETFE are thermal aging, solder, and moisture resistant. Both 30 CF PTFE and ETFE are thermoplastics. Decomposition Temperature. As a result, ETFE solutions therefore initially found use on projects such as botanical gardens, zoological gardens, swimming pools, and exhibitions spaces. It can withstand a wide temperature range, making it suitable for both hot and cold climates. HDPE Cable Insulation.
