ETFEIt is the strongest fluoroplastic. While maintaining the good heat resistance, chemical resistance and electrical insulation properties of PTFE, it also greatly improves the radiation resistance and mechanical properties. The tensile strength can reach 50MPa, which is close to tetrafluoroethylene. 2 times.

 ETFEIt is a good dielectric material with high dielectric strength, 2.6 dielectric constant, high resistivity and only 0.003 low loss factor. Its low dielectric constant is essentially constant over frequency and temperature variations.ETFEThe temperature range is more practical and wider. The constant temperature is typically set between -65°C and 150°C. It is still very hard at ultra-low temperatures, and the embrittlement temperature is as low as -100°C. In additionETFEIt also passed several stringent flame retardancy tests, such as IEEE 383, and received a UL 94 V-0 rating. It has little effect on the physical properties of most chemicals and has low permeability to common gases and moisture.
