Why is PETG resistant to Sodium Chloride?

PETG shows excellent resistance to Sodium Chloride due to its glycol-modified polyester structure providing moderate chemical resistance.

⚠️ When NOT to use PETG

Avoid using PETG with strong acids, alkalis, and most organic solvents. Better impact resistance than PET but lower chemical resistance.
