Why is Polycarbonate resistant to Isooctane?
Polycarbonate shows good resistance to Isooctane 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.
