Polycarbonate / Polyester Blends, Impact Modified PC is a subcategory of Polycarbonate. The additative is added during the manufacturing process. Its flexural modulus ranges from 280 to 325 MPa. Its tensile strength ranges from 7600 to 8500 MPa at break. Its flexural strength ranges from 10900 to 12500 MPa. Its Izod Impact strength ranges from 2 to 18 J/cm. Its elongation at break ranges from 120 to 165 %. Its hardness ranges from 114 to 122 Rockwell R. Its specific gravity ranges from 1.2 to 1.22. Its coefficient of thermal expansion ranges from 80 to 95 x 10-6/°C. Its molding pressure ranges from 15 to 20 MPa.
Polycarbonate, also known as PC, is a thermoplastic polycondensate. Common trade names are Lexan and Makrolon. It has excellent strength, toughness, dimensional stability, dielectric strength, flame retardancy, and impact resistance (highest among transparent rigid materials). It is, however, susceptible to stress cracking with aromatic solvents, and is difficult to machine. PC can be used to make optical lenses, windows, medical items, CD's, and power tool housings. It can also be used in truck cabs.
