ETFE also has a wide temperature range, with the ETFE melting point around 267°C, and a maximum service temperature of 150°C. ETFE efficiently decomposed to F – and CO 2. Density: It has a density in the range of 2. It is highly resistant to corrosion. The dissipation factor of ETFE, measured from -150°C to 210°C, shows two peaks at -80°C and 92°C, which are associated with molecular relaxations.

The chart below shows a technical comparison among these materials. PVF displays several transitions below the melting temperature. Great in a wide range of applications from electrical wire insulators, fluid flow tubing, medical devices, automotive, and hot and cryogenic (-320 F) uses. 1. This improves FEP processing characteristics while maintaining high perfluorination.

Tensile strength: 35 - 50 MPa. apart from the tests at testing temperature T 0 for the ETFE foil from producer III with only three tests per test combination. product's melting point is near room temperature. The ETFE powder material used in this study was supplied by Asahi Glass Company. Tefzel® ETFE has excellent chemical resistance & can be applied as thick as PFA but is the tougher. switches. Maximum use temperature of 300 F (~150 C) Natural ETFE is semi-transparent. As such, the operating temperature of the materials is lower. The ethylene tetrafluoroethylene (ETFE)-alternating copolymer is a melt-processable fluororesin. 45) × ppm. of 1/8 in. ETFE HT-2181 are inert to most solvents and chemicals, hydrolytically stable, and weather-resistant. The recommended upper service temperature is 155 °C (311 °F); useful properties are retained at cryogenic ranges. It has a fairly high density among thermoplastics. INTRODUCTION TO ETFE ETFE is a melt-process able fluoropolymer, belonging to the sub-category of polymer materials called thermoplastics. The melting temperature of PTFE is 327 o C and ETFE 267 o C, but both of these materials begin to soften below at lower temperatures. ETFE (or Ethylene tetraflurorethylene) is a fluorine based plastic, equipped with a high melting point and an excellent chemical, electrical and high energy radiation resistance property. During the historical development of cables, numerous types of insulation have been employed.
