Bayer Makrolon Polycarbonate Sheet are considered unbreakable

Polycarbonate plastic materials have a great blend of useful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is definitely a tough material. Whilst it offers higher impact-resistance, it possesses a lower scratch-resistance and so a hard coating can be applied to polycarbonate eyeglasses and polycarbonate exterior automobile components. The characteristics of polycarbonate are generally comparable to those of Acrylic PMMA materials, yet , polycarbonate is actually 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 several types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Because of this, it could be processed and formed   without needing to be heated using standard sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which can not be crafted from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is frequently found in eye protection, in addition to other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require much higher 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 glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
