Polycarbonate Disk - T 0.175mm Ø 6mm

Details

SKU: 1000043983 Product Code: CT30-FM-000110
Polycarbonate Disk provides high impact resistance, optical clarity, and dimensional stability in a precisely machined circular format. Known for its toughness and resistance to fracture, polycarbonate maintains mechanical integrity under high load and is naturally transparent, allowing use in both protective and optical systems. The disk form is suitable for safety windows in instrumentation, viewing ports in high-pressure vessels, and optical lenses in ruggedized equipment. Industries including aerospace, defense, and manufacturing employ polycarbonate disks in protective shielding, calibration optics, and machine vision systems. Research applications include optical material testing, impact resistance studies, and prototyping of transparent mechanical components. The combination of clarity, strength, and precision geometry ensures polycarbonate disks deliver consistent performance where visibility and resilience are equally critical.
