SABIC LEXAN OQ4320R PC Resin

Physical Properties

• Specific Gravity: Tested per ASTM D792, the material’s specific gravity is 1.20 g/cc, reflecting its density relative to water.
• Water Absorption: After 24 hours per ASTM D570, the material absorbs 0.15%, indicating low short-term moisture uptake.
• Linear Mold Shrinkage, Flow: SABIC method yields 0.0050–0.0070 cm/cm (in/in) flow-direction shrinkage for 3.20 mm (0.126 in) thickness.
• Melt Flow: As per ASTM D1238, the melt flow rate is 12.5 g/10 min under a 1.20 kg (2.65 lb) load at 300 °C (572 °F).

Polymer Properties:

• Base Material: Polycarbonate (PC)
• Modification Features:
  
  • Optical grade with UV cut – off up to 400 nm for effective sun protection.
  • Higher optical purity than standard grades for clear vision.
  • Contains internal mold release for smooth production of optical parts.

Applications:

Given these properties, LEXAN™ OQ4320R is primarily used in the following applications:

• Optical Lenses: It is a preferred material for lenses in cameras, eyewear, and other optical instruments where clarity and precision are non-negotiable.
• Display Windows: The resin is used for transparent windows and shields in electronic displays, monitors, and point-of-sale systems where high clarity and durability are required.
• Lighting Components: Its optical purity and heat resistance make it an excellent material for high-end light guides, lenses, and diffusers in specialized lighting applications.
• Medical and Diagnostic Optics: It is also used for transparent components in medical devices and diagnostic equipment that require high precision and clarity.
