PC 日本帝人 L-1250Y 透明级 耐高温 照明灯具 薄壁制品 (CAS No.None)

Product Name:Polycarbonate (PC) Teijin L-1250Y

English Name:Polycarbonate (PC) Teijin L-1250Y

CAS No.:25037-45-0

Aliases:Polycarbonate, PC, Bisphenol A polycarbonate

Molecular Formula:(C16H14O3)n

Physical Properties:Pure PC resin is an amorphous, transparent thermoplastic polymer with a relative density of 1.18-1.20 and a glass transition temperature of 140-150°C. The decomposition temperature is above 300°C, the long-term working temperature is 120°C, the brittleness temperature is -100°C, and the long-term service temperature ranges from -60°C to 120°C. It has excellent mechanical properties, especially outstanding impact strength and dimensional stability, good chemical and oil resistance, and excellent electrical properties. However, fatigue resistance and abrasion resistance are relatively poor, and it is prone to stress cracking.

Uses:Mainly used in lighting fixtures, thin-wall products, and other fields, suitable for injection-molded parts requiring high transparency and heat resistance, as well as structural components in automotive, electrical, and electronic applications.
