An overview of the ??Big 2?? wiring insulations: PTFE and ETFE

Physical PropertiesThermal PropertiesOutgassingin PracticeReviewThe varieties of PTFE and ETFE wires may not differ incredibly in their construction, however considering the physical properties of both of the polymers, there are some differences between the two. The tensile strength of ETFE can be as much as 34% greater than PTFE. PTFE is more flexible and has a much higher (66%) elongation to break. Additionally, PTFE does have a significant advantage with its coefficient of friction. PTFE has a coefficient of friction one-third of ETFE making it a more.The Many Features and Benefits of Fluoropolymers as Cable .Why do people use fluoropolymers as a cable insulation or jacket material?
