Bayer Makrolon Polycarbonate Flat Sheet are considered unbreakable

Polycarbonate plastic materials give you a unique balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very sturdy material. Although it features very high impact-resistance, it's got minimal scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear as well as polycarbonate exterior motor vehicle components. The properties of polycarbonate tend to be like those of polymethyl methacrylate (PMMA, acrylic), yet , polycarbonate definitely is stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Hence, for small changes in shape, it can be processed and formed   at room temperature using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are essential, which cannot be produced from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is commonly used in eye protection, and also in other projectile-resistant see through applications that would normally indicate the use of glass, but require greater impact-resistance. Many kinds of lenses are made of polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
