Why is PETG resistant to Isopropanol?
PETG shows excellent resistance to Isopropanol 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.
