Applications:

1. Lighting Diffusers
   • Description: URC2500 is widely used in lighting diffusers for LCD and LED applications, thanks to its high reflectivity (97.0%) and low light transmittance (0.6%), which enable efficient light diffusion and shielding.
   • Use Case: Applied in LCD reflective sheets, LED guide light reflectors, and lamp holders for both automotive and general lighting.
   • Data Evidence: The material’s optimized reflectivity and low transmittance properties are ideal for LCD backlight units and LED lighting diffusion covers, ensuring uniform light distribution.
2. Automotive Lighting
   • Description: URC2500 is utilized in automotive lighting components, such as daytime running light (DRL) reflectors. It stands out for its heat resistance (HDT of 138°C at 0.45 MPa) and flame retardancy (UL 94 V-0).
   • Use Case: Employed in reflectors and diffusion covers for headlights and DRL systems.
   • Data Evidence: Its high reflectivity (97.0%) and thermal stability allow it to perform well under the high-temperature conditions common in automotive environments.
3. Electrical and Electronic Components
   • Description: URC2500 is suitable for electrical housings and components due to its excellent electrical properties (including a high dielectric breakdown voltage) and flame-retardant characteristics.
   • Use Case: Used in housings for electronic devices and connectors that require flame resistance.
   • Data Evidence: The UL 94 V-0 rating and a Relative Temperature Index (RTI) of 80°C ensure safety and reliability in electrical applications.
4. Optical Systems (LCD/LED Applications)
   • Description: In optical systems for LCD and LED lighting, URC2500 is used in components like light guide plates and reflective sheets, leveraging its high reflectivity and low light transmittance.
   • Use Case: Applied in LCD backlight units and LED diffusion covers.
   • Data Evidence: The material’s optical properties—97.0% reflectivity and 0.6% transmittance—are crucial for efficient light management in display technologies.
