[1][2] One of the key properties of ECTFE is its permeation resistance to large molecules, which is generally slow and not significant in practical applications.

[3][4] This permeation resistance is particularly critical in lining and coating applications, where the material is used to protect underlying layers, such as fiber-reinforced plastic (FRP) or steel, from corrosive substances.

ECTFE finds applications in various industries due to its favorable chemical resistance properties, providing durable and reliable protection in harsh environments.

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.

[12][full citation needed][13][failed verification] Extrusion of ECTFE fabric-backed sheets and subsequent fabrication into vessels, pipes or valves is done in the chemical industry.

Unlike PTFE, ECTFE can be crimped,[32] which allows its production in the form of nonwoven fibers with high surface area and porosity.
