Why is Polycarbonate resistant to N Heptane?
Polycarbonate shows excellent resistance to N Heptane 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.
