Polycarbonate
Polycarbonate is an amorphous material with excellent impact strength, clarity, and optical properties. Polycarbonate has excellent mechanical properties and can be molded to tight tolerances. Solvents and petrochemicals attack it, and its weatherability is only adequate. Brand names include

Fiber Laser Marking of Plastic: Polycarbonate
Polycarbonates are a particular group of thermoplastic polymers. They are easily worked, moulded, and thermoformed; as such, these plastics are very widely used in many modern industries. Their interesting features, such as temperature resistance, impact resistance and optical properties, position
