SABIC LEXAN 103 PC Resin

Physical Properties

• Specific Gravity: Per ASTM D792, the specific gravity is 1.20 g/cc, with results of two test entries under the same standard being consistent.
• Density: As specified by ASTM D792, the density is 1.19 g/cc (0.0430 lb/in³), determined using the standard testing methodology for accuracy.
• Water Absorption: After 24 hours of testing per ASTM D570, water absorption is 0.15% (0.15%), reflecting the material’s moisture uptake under immersion conditions.
• Moisture Absorption at Equilibrium: Per ASTM D570, moisture absorption is 0.35% at equilibrium and increases to 0.58% at 100 °C (212 °F).
• Linear Mold Shrinkage, Flow: Using the SABIC method for a 3.20 mm (0.126 in) thickness, the linear mold shrinkage (flow direction) of molded components is 0.0050–0.0070 cm/cm (0.0050–0.0070 in/in).
• Melt Flow: Per ASTM D1238, the melt flow rate is 7.0 g/10 min under a 1.20 kg (2.65 lb) load at 300 °C (572 °F), indicating the material’s melt processability.

Polymer Properties:

• Base Material: Polycarbonate (PC)
• Modification Features:
  
  • Heat – resistant for high – temperature environments.
  • Electrically insulating for safe component use.
  • High – strength for structural applications.

Applications:

• Electronics: Ideal for electrical enclosures that protect internal components from heat and external elements and connectors requiring reliable insulation.
• Industrial Equipment: Used in machinery covers that shield operators from moving parts and guards that maintain structural integrity under stress.
• Aerospace (Specialty): For some interior non – structural components like cabin panels that need to meet flame and smoke regulations.
