SABIC LEXAN LS2 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: Per ASTM D570, the material absorbs 0.15% moisture after 24 hours, indicating low short-term water uptake.
• Linear Mold Shrinkage, Flow:Using SABIC method for 3.20 mm (0.126 in) thickness, flow-direction shrinkage is 0.0050–0.0070 cm/cm (in/in).
• Melt Flow: As per ASTM D1238, the melt flow rate is 11 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:
  
  • Medium viscosity offering a balance of flow and mechanical properties.
  • UV – stabilized to withstand outdoor exposure in automotive environments.
  • Transparent colors only, suitable for optical parts in vehicles.

Applications:

Given these properties, LEXAN™ LS2 is primarily used in the following applications:

• LED Lamp Covers and Lenses: Its optical clarity, UV stability, and heat resistance make it an ideal material for the covers and lenses of LED lamps, ensuring both long-term performance and efficiency.
• Light Diffusers: The resin can be used to create sheets or molded parts that diffuse light evenly, eliminating hot spots and providing a more uniform and pleasant lighting experience.
• Street Lighting and Outdoor Fixtures: Its weather resistance and impact strength make it suitable for a wide range of outdoor lighting applications, including streetlights, security lighting, and architectural lighting.
• Architectural Glazing: It can be used for transparent or translucent building panels, skylights, and windows where light transmission and durability are required.
