Polycarbonate is transparent (something which can be seen through) thermoplastic. This material is tough and stable. It can resist a high temperature of 280°F and a low temperature of -40 °F. It is stain resistant and non-toxic. The weight of polycarbonate is one tenth of that of glass.
Industries use clear polycarbonate to make glasses. This is because it has a very good transparency and durability. Lenses made from clear polycarbonate can be thinner than lenses made from ordinary glass.
Companies that make electronic equipment use polycarbonate to make the cover of mobile phones, laptops and other products. Although polycarbonate is not poison, the process of making polycarbonate uses poison chemicals. (See Bisphenol A).
