Polycarbonates plastics are widely used. They can be either hard transparent plastic that can be used to replace glass or a softer, but still tough, semi-opaque plastic used for making plastic boxes and containers or they can be used to make polymer lacquers used to protect metal surface. It is used in water bottles, baby bottles, tableware, and food storage containers.
Polycarbonates are used in food packaging as components of multilayer co-extrusions and co-injections moldings to provide excellent impact strength, heat resistance and transparency.
Although it passes more than 90% of visible rays, it absorbs a sizeable quantity of ultraviolet rays.
Polycarbonate has a melting point of 230 °C and brittle temperature of -100 °C. This means that polycarbonate has significantly better heat and cold resistance than ordinary polymers.
