Physical Properties

• Bulk Density: Measured per ISO 60, bulk density is 0.660 g/cc (0.0238 lb/in³), indicating packed material mass per unit volume.
• Density: Determined by ISO 1183-1, density is 1.20 g/cc (0.0434 lb/in³), reflecting a compact structure for dense applications.
• Water Absorption at Saturation: Tested to ISO 62, values are 0.30% and 0.35%, showing moderate moisture resistance in saturated conditions.
• Water Vapor Transmission: At 85% RH (100 µm film, ISO 15106-1), rate is 15.0 g/m²/day (0.966 g/100 in²/day) for controlled permeability.
• Oxygen Transmission: For 100 µm film (ISO 2556), 800 cc·mm/m²·24hr·atm; 25.4 µm film shows 3150 cc·mm, indicating thickness affects gas flow.
• Nitrogen Transmission: 100 µm film (ISO 2556) gives 160 cc·mm; 25.4 µm film rises to 630 cc·mm/m²·24hr·atm, showing thickness-dependent permeability.
• Carbon Dioxide Transmission: 100 µm film (ISO 2556) at 4800 cc·mm; 25.4 µm film reaches 18900 cc·mm/m²·24hr·atm, highlighting CO₂ permeability variation.
• Linear Mold Shrinkage (Parallel/Normal): Per ISO 2577, ranges 0.0050–0.0070 cm/cm, indicating moderate dimensional change in molding.
• Linear Mold Shrinkage, Flow: For 60x60x2 mm (ISO 294-4), flow shrinkage is 0.0065 cm/cm, higher along material flow direction.
• Linear Mold Shrinkage, Transverse: Same conditions yield 0.0070 cm/cm, showing minimal shrinkage perpendicular to flow.
• Melt Flow: At 300 °C/1.20 kg (ISO 1133), melt flow rate is 20 g/10 min, suitable for efficient injection molding processes.
