Polycarbonate is the impact-resistant transparent thermoplastic. It absorbs energy without shattering and machines or molds beautifully. Tradeoffs: poor solvent resistance, susceptibility to UV without stabilizers.

- Lab safety windows and visors.
- Medical and lighting components.
Solvent stress cracking
PC stress-cracks in contact with strong solvents. Avoid acetone, MEK, gasoline. Use PC-FR (flame retardant) for electrical applications and UV-stabilized grade for outdoor.
Specifying it on Uretyco
