Clear Polycarbonate tube is a very durable material. Although it has high impact-resistance, it has low scratch-resistance and so a hard coating can be applied for added protection. Polycarbonate characteristics are quite like those of polymethyl methacrylate (PMMA, ACRYLIC), but polycarbonate is stronger, usable in a wider temperature range.
Polycarbonate is a versatile, tough plastic used for a variety of applications, from bulletproof windows to compact disks (CDs). It comes in transparent and opaque varieties.
