Why is Polycarbonate resistant to Potassium Sulfate?
Polycarbonate shows excellent resistance to Potassium Sulfate 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.
