Covestro Makrolon Polycarbonate Flat Sheet are considered unbreakable
Makrolon Polycarbonate products give you a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a durable material. Although it features tremendous impact-resistance, it has a lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eyewear lenses as well as polycarbonate exterior vehicle components. The properties of polycarbonate tend to be along the lines of those of Acrylic PMMA materials, although polycarbonate is undoubtedly 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 many different types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking or cracking. For this reason, for small changes in shape, it can be processed and formed cold using standard sheet metal techniques, such as forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are important, which can't be created from sheet metal. Understand that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent with out a heating process.
Polycarbonate is often utilized in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally require the use of glass, but require much higher impact-resistance. Many different types 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 made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
