Ethylene-Chlorotrifluoroethylene (ECTFE) is a costly, semi-crystalline, melt processable, whitish semi-opaque thermoplastic with good barrier properties and chemical resistance.
In addition, the thermoplastic has good high frequency electrical characteristics and good creep and tensile properties.
Advantages of Ethylene-Chlorotrifluoroethylene include:
- Melt processable
- Good high frequency electrical characteristics.
- Inherent fire retardance.
- Good creep and tensile properties (comparable to Nylon 6/6).
- Good radiation and wear resistance.
Ethylene-Chlorotrifluoroethylene can be extremely expensive and can be attacked by esters & aromatic hydrocarbons.
Applications of Ethylene-Chlorotrifluoroethylene (ECTFE) include cable covering, barrier films, release/vacuum bagging films, valve and pump components, filaments for weaving into fabric, film, flexible circuitry, tubing for optical fibers, and chemically resistant linings etc.
Ethylene-Chlorotrifluoroethylene is fire retardant which makes it perfect for cable covering. Image Credit: ShutterStock/Flegere
