Physical Properties

  • Bulk Density:Measured for pellets per ISO 60, the bulk density is 0.660 g/cc (0.0238 lb/in³), indicating packing density in granular form.
  • Density:Determined by ISO 1183, the density is 1.20 g/cc (0.0434 lb/in³), a fundamental mass-to-volume property for material characterization.
  • Moisture Absorption at Equilibrium:At equilibrium per ISO 62, moisture absorption is 0.12%, ensuring stability in 50% relative humidity environments.
  • Water Absorption at Saturation:As per ISO 62, water absorption at saturation is 0.30%, critical for assessing long-term water exposure resistance.
  • Water Vapor Transmission:For a 100 µm film at 85% RH (ISO 15106-1), the rate is 15.0 g/m²/day (0.966 g/100 in²/day), measuring moisture barrier performance.
  • Oxygen Transmission:
    • 100 µm film: 700 cc-mm/m²-24hr-atm (1780 cc-mil/100 in²-24hr-atm) per ISO 2556.
    • 25.4 µm film: 3150 cc-mm/m²-24hr-atm (8000 cc-mil/100 in²-24hr-atm) per ISO 2556.
  • Nitrogen Transmission:
    • 100 µm film: 130 cc-mm/m²-24hr-atm (330 cc-mil/100 in²-24hr-atm) per ISO 2556.
    • 25.4 µm film: 630 cc-mm/m²-24hr-atm (1600 cc-mil/100 in²-24hr-atm) per ISO 2556.
  • Carbon Dioxide Transmission:
    • 100 µm film: 4000 cc-mm/m²-24hr-atm (10200 cc-mil/100 in²-24hr-atm) per ISO 2556.
    • 25.4 µm film: 18900 cc-mm/m²-24hr-atm (48000 cc-mil/100 in²-24hr-atm) per ISO 2556.
  • Linear Mold Shrinkage, Flow:For 60x60x2 mm samples at 500 bar (ISO 294-4/2577), flow shrinkage is 0.0065 cm/cm (0.0065 in/in).
  • Linear Mold Shrinkage, Transverse:At 500 bar pressure (ISO 294-4/2577), transverse shrinkage is 0.0070 cm/cm (0.0070 in/in) for 60x60x2 mm samples.
  • Melt Flow:Per ISO 1133, the melt flow rate is 20 g/10 min at 300°C (572°F) under a 1.20 kg (2.65 lb) load, reflecting processability in molding.
