30% 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 250 to 2150 MPa. Its flexural modulus ranges from 240 to 1900 MPa. Its tensile strength ranges from 20000 to 24000 MPa at break. Its flexural strength ranges from 30000 to 36000 MPa. Its compressive strength ranges from 19000 to 26000 MPa. Its elongation at break ranges from 1 to 5 %. Its hardness ranges from 118 to 119 Rockwell R. Its specific gravity ranges from 1.32 to 1.33. Its melting temperature ranges from 149 to 150 °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.
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 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, 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.
