• Bulk Density: Measured per ISO 60 for pellets, bulk density is 0.660 g/cc (0.0238 lb/in³), reflecting material packing density in granular form.
• Density: Determined by ISO 1183-1, the density is 1.20 g/cc (0.0434 lb/in³), a key parameter for mass-to-volume ratio in material design.
• Moisture Absorption at Equilibrium: At 50% RH per ISO 62, moisture absorption is 0.12%, ensuring dimensional stability in humid environments.
• Water Absorption at Saturation: As per ISO 62, water absorption at saturation is 0.30%, critical for assessing long-term water resistance in applications.
• Water Vapor Transmission: For 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 efficiency.
• Oxygen Transmission: Per ISO 2556 gas permeability analysis, 100 µm film has 700 cc-mm/m²-24hr-atm (1780 cc-mil/100 in²/day) and 25.4 µm film has 3150 cc-mm/m²-24hr-atm (8000 cc-mil).
• Nitrogen Transmission: For inert gas barrier evaluation per ISO 2556, a 100 µm film shows 130 cc-mm/m²-24hr-atm (330 cc-mil) and a 25.4 µm film shows 630 cc-mm/m²-24hr-atm (1600 cc-mil) gas permeability.
• Carbon Dioxide Transmission: For packaging applications per ISO 2556, a 100 µm film has 4000 cc-mm/m²-24hr-atm (10200 cc-mil) and a 25.4 µm film has 18900 cc-mm/m²-24hr-atm (48000 cc-mil) gas permeability.
• Linear Mold Shrinkage: Ranges 0.0050–0.0070 cm/cm (in/in) per ISO 2577, indicating typical dimensional change during injection molding.
• Linear Mold Shrinkage, Flow: For 60x60x2 mm samples at 500 bar (ISO 294-4), flow shrinkage is 0.0065 cm/cm (in/in) along processing direction.
• Linear Mold Shrinkage, Transverse: At 500 bar (ISO 294-4), transverse shrinkage is 0.0070 cm/cm (in/in) across processing direction for molded parts.
• Melt Flow: Per ISO 1133, melt flow rate is 20 g/10 min at 300°C (572°F) under 1.20 kg (2.65 lb) load, reflecting processability in extrusion/molding.
