ETFE is commonly used in the nuclear industry for tie or cable wraps and in the aviation and aerospace industries for wire coatings. This is because ETFE has better mechanical toughness than PTFE. In addition, ETFE exhibits a high-energy radiation resistance and can withstand moderately high temperatures for a long period.
In physics, the term dielectric strength has the following meanings: . for a pure electrically insulating material, the maximum electric field that the material can withstand under ideal conditions without undergoing electrical breakdown and becoming electrically conductive (i.e. without failure of its insulating properties).
In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett.While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining.
Ethylene tetrafluoroethylene (ETFE), in many ways, can be thought of as belonging to a different group, as it is essentially a high strength engineering version of the others featuring what are likely to be considered slightly diminished properties in the other fields when compared with PTFE, FEP and PFA.
Cable ties made of ETFE (Tefzel) are used in radiation-rich environments. Red cable ties made of ECTFE (Halar) are used for plenum cabling . Stainless steel cable ties are also available for flameproof applications—coated stainless ties are available to prevent galvanic attack from dissimilar metals (e.g. zinc -coated cable tray).
The CEO of investment firm Azoria lobbied DOGE figurehead Elon Musk to have the department issue stimulus checks from some of the claimed $55 billion in savings.
ECTFE has a continuous usage temperature range between –76°C and +150°C (–105°F to +300°F). It has strong impact resistance and a Young's modulus in the range of 1700 MPa, [5] allowing for self-standing items and pressure piping systems.
Many big companies are pulling workers back to the office five days a week. The Big Four — EY, Deloitte, PwC, and KPMG — are sticking with hybrid work policies.
