20 - 30% Long Glass Fiber Reinforced Flame-Retardant Grade PC is a subcategory of Polycarbonate. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 1000 to 1100 MPa. Its flexural modulus ranges from 900 to 1200 MPa. Its tensile strength ranges from 14000 to 20000 MPa at break. Its flexural strength ranges from 21000 to 30000 MPa. Its compressive strength ranges from 18000 to 21000 MPa. Its Izod Impact strength ranges from 1.8 to 2 J/cm. Its elongation at break ranges from 2 to 3 %. Its hardness ranges from 77 to 85 Rockwell M. Its specific gravity ranges from 1.36 to 1.45.
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.
