Unfilled Molding and Extrusion Resins, High Viscosity PC is a subcategory of Polycarbonate. The additative is added during the manufacturing process. Its flexural modulus ranges from 330 to 340 MPa. Its tensile strength ranges from 9100 to 10500 MPa at break. Its flexural strength ranges from 12500 to 13500 MPa. Its compressive strength ranges from 10000 to 12500 MPa. Its Izod Impact strength ranges from 12 to 18 J/cm. Its elongation at break ranges from 110 to 120 %. Its hardness ranges from 70 to 75 Rockwell M. Its molding pressure ranges from 10 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.
