40% PAN Carbon Fiber EMI Shielding (conductive) PC is a subcategory of Polycarbonate. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 3000 to 3100 MPa. Its flexural modulus ranges from 2800 to 2900 MPa. Its tensile strength ranges from 23000 to 24000 MPa at break. Its flexural strength ranges from 34000 to 35000 MPa. Its Izod Impact strength ranges from 1.5 to 2 J/cm. Its elongation at break ranges from 1 to 2 %. Its specific gravity ranges from 1.36 to 1.38. Its coefficient of thermal expansion ranges from 11 to 14.4 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.
