CAS 25037-45-0 corresponds to polycarbonate, which is an amorphous thermoplastic engineering plastic synthesized from bisphenol A as raw material. Its scientific name is 2,2-bis (4-hydroxyphenyl) propane polycarbonate.

Core Basic Information
-Chinese name: Polycarbonate (scientific name: 2,2-bis (4-hydroxyphenyl) propane polycarbonate)
-English name: Polycarbonate (PC)
-CAS number: 25037-45-0
-Material form: non-toxic, odorless, colorless to light yellow transparent solid (amorphous polymer, no clear melting point, melting at 220-230 ℃)
-Key features: high light transmittance (>85%~90%), high impact toughness, heat resistance (thermal deformation temperature 130~140 ℃), dimensional stability, good electrical insulation

Main physical and chemical properties
1. Density: Approximately 1.18-1.22 g/cm ³
2. Heat resistance: Long term use temperature -60~120 ℃, glass transition temperature is about 149 ℃
3. Optical performance: The transmittance can reach over 90%, and the refractive index is about 1.586~1.594
4. Solubility: soluble in chlorinated solvents such as dichloromethane and p-dioxane; Not resistant to strong alkalis and ketones, easily hydrolyzed by long-term boiling water
5. Mechanical performance: Excellent impact resistance (with a notch free impact strength of over 4.5 MPa), but poor fatigue and stress cracking resistance

Main application areas
-Optics and Electronics: Optical Disc Substrate, Lens, Display Screen Protective Cover, Electronic Appliance Shell
-Medical and Food: Medical Devices, Dialysis Membrane, High Temperature Sterilizable Containers (subject to migration regulations)
-Architecture and transportation: daylighting panels, riot glass, car lampshades, aviation transparent components
-Other: Fiber optics, safety masks, precision mechanical parts (often modified by blending with ABS, etc.)
