Why is Polycarbonate resistant to Water Glass?
Polycarbonate shows excellent resistance to Water Glass 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.
