Why is FEP resistant to Zinc Oxide?
FEP shows excellent resistance to Zinc Oxide due to its fully fluorinated structure similar to PTFE, offering near-universal chemical resistance.
⚠️ When NOT to use FEP
Avoid using FEP (Fluorinated Ethylene Propylene) with molten alkali metals and fluorine gas. Suitable up to 200°C.
