Compatibility Rating
Why is Polycarbonate resistant to Propylene Glycol?
Polycarbonate shows good resistance to Propylene Glycol due to its carbonate group structure, though it has limited chemical resistance compared to other engineering plastics.
⚠️ When NOT to use Polycarbonate
Avoid using Polycarbonate with alkalis, amines, ketones, esters, and many organic solvents. Prone to stress cracking.
