What is Polycarbonate (PC)?

Polycarbonate (PC) is a type of polymer that is made from monomers called phosgene and bisphenol A. It is a synthetic polymer that is known for its excellent mechanical and thermal properties, as well as its good electrical insulation properties.

Polycarbonate is a transparent, amorphous polymer that has a high melting temperature and a high modulus of elasticity. It has excellent impact resistance and is resistant to a wide range of chemicals, including acids, bases, and organic solvents. It is also resistant to UV radiation and weathering, making it a good choice for outdoor applications.

Polycarbonate is a versatile material that is used in a wide range of applications, including the aerospace, automotive, and electronics industries. It is also used in the production of seals, gaskets, and other sealing products, due to its excellent chemical resistance and low coefficient of friction.

Polycarbonate - Key Properties

There are several types of polycarbonates, including bisphenol A polycarbonate (PC-A), bisphenol F polycarbonate (PC-F), and bisphenol S polycarbonate (PC-S). Each type of polycarbonate has its own unique properties and is used in different applications. For example, PC-A is a strong and tough material that is used in applications where high strength and toughness are required, while PC-F is a more flexible and elastic material that is used in applications where flexibility and elasticity are required.
