Polycarbonate (PC) Spheres
Product Description
Our polycarbonate spheres are precision-manufactured from virgin-grade PC resin, delivering outstanding clarity, dimensional accuracy, and mechanical toughness. Unlike glass or acrylic balls, PC spheres offer superior shatter resistance and are significantly lighter — making them ideal for lighting fixtures, flow visualization, display props, sensor housings, and ball valve components.
Available in solid or hollow form, with optional UV stabilization and custom colors. Tight dimensional tolerances (±0.1 mm standard) ensure drop-in compatibility with standard fittings.
