LEXAN™ OQ4820 Polycarbonate Resin. Transparent Custom Color. Low Flow
UV Cutoff, Ophthalmic Lenses, High Refractive Index with UV Stabilizer
Lighter Eyewear, enhanced UV Protection, and excellent Optical performance are Key requirements in Today's Ophthalmic Market. LEXAN™ OQ4820 Polycarbonate Resin Was developed to meet these demands by combining Optical-Grade Purity, UV 400 Nm Protection, and High Refractive Index performance within a specialized Polycarbonate formulation designed for Premium Lens applications.
As an Optical Quality Resin, LEXAN™ OQ4820 Polycarbonate Resin delivers Outstanding Transparency and Visual Accuracy. The material is suitable for Ophthalmic Lenses where Clear Vision, Minimal Distortion, and Long-Term Optical Consistency are Essential.
Manufacturers can Utilize LEXAN™ OQ4820 Resin to produce Lenses that maintain High Visual Standards while Benefiting from the Toughness Associated with Polycarbonate Technology.
A Major Advantage of LEXAN™ OQ4820 Polycarbonate Resin is its UV 400 Nm Cutoff Formulation. This Built-In Protection helps Block Harmful Ultraviolet Radiation, making the material particularly attractive for Sunwear and Protective Eyewear applications. The addition of a UV Stabilizer further supports Color Retention and Long-Term Durability during exposure to Sunlight.
Unlike High-Flow Optical Grades optimized for Maximum Productivity, LEXAN™ OQ4820 Polycarbonate Resin features a Low-Flow Processing Profile, providing enhanced Processing Control and excellent Replication of Optical Surfaces. This Characteristic is especially valuable when producing High-Precision Ophthalmic components that require Stringent Quality Standards.
The High Refractive Index offered by LEXAN™ OQ4820 Resin enables Thinner and Lighter Lens Constructions while maintaining Optical Effectiveness. This contributes to improved Wearer Comfort and Modern Lens Aesthetics, making the Resin suitable for Advanced Eyewear Designs.
LEXAN™ OQ4820 Polycarbonate Resin is Supplied as a , Reflecting its Primary Focus on Optical and Ophthalmic performance rather than Flame-Retardant applications.
LEXAN™ OQ4820 Polycarbonate Resin is also RoHS Compliant, supporting Global Environmental and Regulatory Requirements.
