20 - 30% Long Glass Fiber Reinforced PC is a subcategory of Polycarbonate. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 1200 to 1500 MPa. Its flexural modulus ranges from 800 to 1500 MPa. Its tensile strength ranges from 18000 to 23000 MPa at break. Its flexural strength ranges from 22000 to 36900 MPa. Its compressive strength ranges from 18000 to 29800 MPa. Its Izod Impact strength ranges from 3.5 to 4.7 J/cm. Its elongation at break ranges from 1.9 to 3 %. Its hardness ranges from 85 to 95 Rockwell M. Its specific gravity ranges from 1.34 to 1.43. Its molding pressure ranges from 10 to 30 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.
