Polycarbonate Copolymer High Heat PC is a subcategory of Polycarbonate. The additative is added during the manufacturing process. Its elastic modulus ranges from 320 to 340 MPa. Its flexural modulus ranges from 320 to 340 MPa. Its tensile strength ranges from 8300 to 10000 MPa at break. Its flexural strength ranges from 12000 to 14000 MPa. Its Izod Impact strength ranges from 1.5 to 12 J/cm. Its elongation at break ranges from 70 to 90 %. Its hardness ranges from 75 to 91 Rockwell M. Its specific gravity ranges from 1.14 to 1.18. Its coefficient of thermal expansion ranges from 70 to 76 x 10-6/°C. Its melting temperature ranges from 160 to 205 °C. Its molding pressure ranges from 8 to 20 MPa.
Polycarbonate, also known as PC, is a thermoplastic polycondensate. Common trade names are Lexan and Makrolon. copolymer 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.
Other common Polycarbonate (PC) include Unfilled Molding and Extrusion Resins, High Viscosity PC, Unfilled Molding and Extrusion Resins, Low Viscosity PC, 10% Glass Fiber Reinforced PC, 30% Glass Fiber Reinforced PC, 20 - 30% Long Glass Fiber Reinforced PC, 40% Long Glass Fiber Reinforced PC, 50% Long Glass Fiber Reinforced PC, 35% Random Glass Mat PC, 20 - 30% Long Glass Fiber Reinforced Flame-Retardant Grade PC, Polyester Copolymer High Heat PC, Polycarbonate / Polyester Blends, Impact Modified PC, 6% Stainless Steel Fiber Conductive PC, 10% Stainless Steel Fiber EMI Shielding (conductive) PC, 20% PAN Carbon Fiber EMI Shielding (conductive) PC, 30% PAN Carbon Fiber EMI Shielding (conductive) PC, 40% PAN Carbon Fiber EMI Shielding (conductive) PC, 10-15% PTFE Lubricated PC, 30% PTFE Lubricated PC, 10-15% PTFE, 20% Fiber Reinforced Lubricated PC, and 2% Silicone, 30% Glass Fiber Reinforced Lubricated PC.
