Technical Features & Advantages

Blue Light Management Features:

   Precise Filtering:** Selectively absorbs high-energy blue light in the 415-455nm band while retaining beneficial blue light.

   Color Fidelity Technology:** Special formulation minimizes color shift, achieving ≥95% object color fidelity (CIE standard).

   Enhanced Visual Comfort:** Smooth transmission spectrum reduces glare and visual fatigue.

Comprehensive Performance Advantages:

1.  Eye Health: Reduces visual strain during prolonged exposure to screens or lighting.

2.  High Clarity & Transparency: Maintains high transparency while filtering harmful blue light.

3.  Durable & Safe:Retains inherent PVC properties: flame retardancy, impact resistance, and chemical resistance.

4.  Easy Processing:Compatible with standard processing techniques for high-transparency PVC sheets.

Application Field Guide

Application Scenario	Recommended Thickness	Functional Requirements	Comparison with Alternatives
LED Display Front Covers	3-5mm	Anti-glare, blue-light reduction, high transparency	Standard Acrylic: No blue-light filtering
Eye-protecting Desk Lamps / Panel Lamp Covers	2-3mm	Blue-light filtering, light diffusion	Frosted Acrylic: Significant light transmittance loss
Electronic Device Viewing Windows	3-5mm	Anti-static, blue-light reduction	Standard Transparent PC: Higher cost, poorer flame retardancy
Museum/Gallery Display Cases	5-8mm	UV blocking, anti-reflection	Laminated Glass: Heavy, difficult installation
Medical Equipment Observation Windows	5-10mm	High transparency, color fidelity, easy cleaning	Standard Medical PVC: No spectral modulation

Processing & Usage Guidelines

Processing Considerations:

   Cutting: Use sharp carbide tools; recommended linear speed: 150-200 m/min.

   Thermoforming: Forming temperature: 135-150°C; ensure uniform heating to avoid optical distortion.

   Bonding: Recommend UV-curing adhesive or epoxy resin adhesive for transparent joints.

   Surface Treatment: Can be treated with AR (Anti-Reflection) coating or AG (Anti-Glare) coating.

Optical Selection Suggestions:

   Blue Light Filtering Rate Selection:

       30%-35%: Mild filtering, suitable for general display devices.

       40%-45%: Moderate filtering, suitable for long-duration work environments.

       50%+: Deep filtering, suitable for specially sensitive individuals.

   Transmittance Balance: For every 10% increase in filtering rate, transmittance decreases by approximately 2-3%.

Maintenance & Care

1.  Clean with a soft cotton cloth and mild detergent; avoid solvents like alcohol or acetone.

2.  Store away from sharp objects to prevent surface scratches.

3.  For long-term outdoor use, inspect the surface condition every 2-3 years.

4.  Avoid prolonged exposure to environments above 70°C.
