• Oxygen Transmission: 100 µm film: 650 cc-mm/m²-24hr-atm (1650 cc-mil) per ISO 2556; 25.4 µm film: 2760 cc-mm/m²-24hr-atm (7010 cc-mil).
• Nitrogen Transmission: 100 µm film: 120 cc-mm/m²-24hr-atm (305 cc-mil) per ISO 2556; 25.4 µm film: 510 cc-mm/m²-24hr-atm (1300 cc-mil).
• Carbon Dioxide Transmission: 100 µm film: 3800 cc-mm/m²-24hr-atm (9650 cc-mil) per ISO 2556; 25.4 µm film: 16900 cc-mm/m²-24hr-atm (42900 cc-mil).
• Linear Mold Shrinkage: Ranges 0.0060–0.0080 cm/cm (in/in) parallel/normal per ISO 2577, indicating typical dimensional change in molding.
• Linear Mold Shrinkage, Flow: For 60x60x2 mm samples at 500 bar (ISO 294-4), flow shrinkage is 0.0065 cm/cm (0.0065 in/in).
• Linear Mold Shrinkage, Transverse: At 500 bar (ISO 294-4), transverse shrinkage is 0.0070 cm/cm (0.0070 in/in) for molded parts.
• Melt Flow: Per ISO 1133, melt flow rate is 10 g/10 min at 300°C (572°F) under 1.20 kg (2.65 lb) load, reflecting processability in molding.

Polymer Properties:

1. Base Material: Polycarbonate (PC)
2. Modification Features:
   
   • High – speed processing and high – strength combination.
   • Good heat and chemical resistance.
   • Excellent surface quality for parts with strict aesthetic requirements.
