What is the difference between ETFE and ECTFE?

ETFE offers excellent chemical resistance with good mechanical strength. It's transparent and recyclable, commonly used for architectural glazing and chemical processing. ECTFE has superior chemical resistance, especially to chlorinated solvents. It offers better permeation resistance and is preferred for aggressive chemical environments.

When should I use ETFE instead of ECTFE?

Use ETFE for: Architectural applications, wire insulation, solar panel covers, general chemical processing where transparency is valued. Use ECTFE for: Aggressive chemical environments, chlorinated solvent handling, tank linings, exhaust systems with acid fumes.

Which has better chemical resistance: ETFE or ECTFE?

ETFE has 352 chemicals rated Excellent (A) at 20°C, while ECTFE has 352. Including Good (B) ratings, ETFE is compatible with 373 chemicals and ECTFE with 373.
