聚碳酸酯 (CAS No.None)
- 物化性质
- 聚碳酸酯是一种无定形热塑性塑料，具有优异的光学透明度（透光率约88%），密度约1.2 g/cm³，玻璃化转变温度约147°C，熔融温度约230°C。它具有良好的耐热性、耐寒性和电绝缘性，尺寸稳定性高，但对紫外光敏感，长期暴露会黄变。溶于二氯甲烷、氯仿等卤代烃，不溶于水、醇和大多数脂肪烃。
- 密度
- 1.19-1.24 g/cm³

Product Name:Polycarbonate
English Name:Polycarbonate
CAS No.:25037-45-0
Aliases:PC, Lexan, Makrolon
Molecular Formula:(C15H16O2)n
Physical Properties:Polycarbonate is an amorphous thermoplastic with excellent optical transparency (transmittance ~88%), a density of approximately 1.2 g/cm³, a glass transition temperature of about 147°C, and a melting temperature of approximately 230°C. It exhibits good heat resistance, low-temperature toughness, and electrical insulation properties with high dimensional stability, but is sensitive to UV radiation and yellows upon prolonged exposure. It is soluble in halogenated hydrocarbons such as dichloromethane and chloroform, and insoluble in water, alcohols, and most aliphatic hydrocarbons.
Uses:Polycarbonate is widely used in electrical and electronic products, automotive, aerospace, and medical devices, suitable for manufacturing meter housings, telescope housings, camera housings, equipment enclosures, computer components, precision instrument parts, distribution boards, power tool housings, and automotive parts. Glass-fiber reinforced PC offers enhanced strength, rigidity, and dimensional stability, improving stress-crack resistance, and is commonly used for bearing retainers, guide rails, gears, and high-performance components such as astronaut helmets.
Technical Specifications:
Density: 1.19-1.24 g/cm³
Light transmittance: approximately 88% (3 mm thickness)
Glass transition temperature: approximately 147°C
Heat deflection temperature: 120-145°C (1.82 MPa)
Izod impact strength: ≥600 J/m (23°C, 3.2 mm thickness)
