　　Polycarbonate PC G-3510 in stock from Teijin Japan

　　Polycarbonate PC

　　Polycarbonate， Known as PC. A thermoplastic with excellent comprehensive performance, it has good heat resistance, cold resistance, and maintains high mechanical strength over a wide temperature range (-135 ℃ -+120 ℃). It has good dimensional stability, with a linear size increase of 0.07% when the temperature rises to 105 ℃. It has high impact strength, good ductility, uniform molding shrinkage, low water absorption, and only gains 0.13% weight after soaking in water for 24 hours. However, it is not easy to machine, and injection molding is the most commonly used method.

　　Polycarbonate (PC)

　　The density is 1.20kg/m3, and the natural color is light yellow. After adding light blue, a colorless transparent product is obtained. Nd=1.586, VD=34.0, and the transmittance is 88%. The mechanical properties of PC are tough and rigid, and the impact strength without notches ranks among the top in thermoplastic materials. The molding shrinkage rate is stable at 0.5% -0.7%.

　　Mechanical properties of polycarbonate (PC) \ Thermal properties of polycarbonate (PC)

　　PC is resistant to corrosion from dilute acids, oxidants, reducing agents, salts, oils, and fatty hydrocarbons at room temperature. It is not resistant to corrosion from alkalis, amines, ketones, and aromatic hydrocarbons. It swells in many organic liquids as vapor and causes stress cracking. It is soluble in dichloromethane, chloramphenicol ethane, cresol, and dioxane, and can hydrolyze and break in water over time, leading to embrittlement.

　　The normal moisture absorption of PC in water is 0.15%, in warm water it is 0.35%, in boiling water it is 0.58%, and it can withstand a water temperature of 60 degrees Celsius.

　　Due to the similar optical constants of PC and PS, it can be combined with PMMA to form an achromatic lens.
