SABIC LEXAN LS1 PC Resin

Physical Properties

• Specific Gravity: Measured per ASTM D792, the material’s specific gravity is 1.20 g/cc, indicating its density relative to water.
• Water Absorption: After 24 hours per ASTM D570, the material absorbs 0.15%, showing low moisture uptake in short-term conditions.
• Linear Mold Shrinkage, Flow: Using the SABIC method for 3.20 mm (0.126 in) thickness, flow-direction shrinkage ranges from 0.0050–0.0070 cm/cm (0.0050–0.0070 in/in).
• Melt Flow: According to ASTM D1238, at 300 °C (572 °F) under a 1.20 kg (2.65 lb) load, the melt flow rate is 17.5 g/10 min.

Polymer Properties:

• Base Material: Polycarbonate (PC)
• Modification Features:
  
  • Low viscosity, enabling easy processing for automotive lens manufacturing.
  • UV – stabilized to resist degradation from sunlight in automotive use.
  • Only available in transparent colors for optical applications.

Applications:

Due to its unique combination of optical clarity and high flow, LEXAN LS1 PC is commonly used for:

• LED Lighting Components: Lenses, diffusers, and light pipes for both residential and commercial LED fixtures. Its ability to mold thin sections accurately is crucial for efficient light distribution.
• Display and Panel Applications: Transparent display shields, screens, and light guides for consumer electronics, such as digital cameras, TVs, and mobile devices.
• Optical Lenses: Lenses for projectors, cameras, and scanners where clarity and precision are paramount.
