PC日本帝人L-1250Z热稳定pc 抗紫外线照明灯具 (CAS No.None)

Product Name:Teijin Panlite L-1250Z Polycarbonate

English Name:Teijin Panlite L-1250Z Polycarbonate

CAS No.:25037-45-0

Aliases:Polycarbonate, PC resin, Heat-stabilized UV-resistant PC

Molecular Formula:(C15H16O2)n

Physical Properties:Transparent thermoplastic engineering plastic with a density of approximately 1.2 g/cm³. Excellent optical performance, refractive index of 1.585 (ASTM D-542). High mechanical strength: tensile strength at yield 62 MPa and at break 80 MPa (ASTM D-638), flexural modulus 2230 MPa (ASTM D-790), Izod notched impact strength of 880 J/m at 3.2 mm thickness (ASTM D-256). Good thermal stability with heat deflection temperature of 132°C under 1.81 MPa load (ASTM D-648) and coefficient of linear expansion of 7×10⁻⁵ cm/cm/°C. Excellent electrical insulation with volume resistivity of 3×10¹⁶ Ω·cm (ASTM D-257) and dielectric strength of 30 kV/mm at 1.6 mm thickness (ASTM D-149). Low water absorption and mold shrinkage of 0.5~0.7%.

Uses:Suitable for electrical and commercial equipment components (computer parts, connectors, etc.), household appliances (food processors, refrigerator drawers, etc.), and transportation industry parts (vehicle headlamps, taillamps, and instrument panels). With heat-stabilized and UV-resistant properties, this grade is particularly well-suited for lighting fixtures.
