ETFE is the strongest fluoroplastic. While maintaining the good heat resistance, chemical resistance and electrical insulation properties of PTFE, the radiation resistance and mechanical properties have been greatly improved, which is close to twice that of polytetrafluoroethylene. It is a tough material with a good balance of various mechanical properties - extremely strong tear resistance, high tensile strength, medium hardness, excellent impact resistance, and long stretch life. ETFE is a good dielectric material with high dielectric strength, dielectric constant of 2.6, high resistivity and low dissipation factor, only 0.003. Its low dielectric constant is essentially constant over frequency and temperature variations. ETFE has a wider and more practical temperature range. The constant temperature is usually set between -65°C and +150°C. It is still extremely hard at ultra-low temperatures, and its embrittlement temperature is as low as -100°C. Has little effect on the physical properties of most chemicals and has low permeability to common gases and moisture.
