To protect your phone from breaking, but obviously if you throw it off a cliff it will break and if you leave it in a pool of water it will break to because the water will slowly get through the gaps of plastic.
Polycarbonate is naturally transparent, with the ability to transmit light nearly that of glass. It has high strength, toughness, heat resistance, and excellent dimensional and colour stability. Flame retardants can be added to polycarbonate without significant loss of properties. It is used for the casing to be able to hold the phone together.
Polycarbonate panels are used as substitutes for glass and plastic such as in windows. You can purchase polycarbonate panels from retailers such as Amazon.
Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) - A blend of PC and ABS that creates a stronger plastic. Used in car interior and exterior parts, and mobile phone bodies.
Polycarbonate is used in a phone because it needs a hard texture of plastic to keep it protected incase it falls or smashes.
Plastic in phones is typically made from polymers derived from petrochemicals, such as polyethylene (PE) or polycarbonate (PC). These polymers are molded and shaped to form the outer casing and components of the phone. Additionally, plastic resins and additives may be used to enhance properties like durability, flexibility, or color.
