LyondellBasell Lupolen 5236 HX HDPE Resin

Physical Properties

• Density: The density is 0.952 g/cc (0.0344 lb/in³), a critical property influencing material weight and structural design in manufacturing.
• Water Absorption: Water absorption is 0.010%, demonstrating low hygroscopicity and stability in moist environments.
• Moisture Absorption at Equilibrium: At equilibrium, moisture absorption is 0.10%, indicating moderate moisture uptake under prolonged humidity exposure.
• Linear Mold Shrinkage, Flow: Linear mold shrinkage in the flow direction is 0.023 cm/cm (0.023 in/in), essential for predicting dimensional accuracy in injection-molded parts.
• Linear Mold Shrinkage, Transverse: linear mold shrinkage is 0.024 cm/cm (0.024 in/in), reflecting slight differential shrinkage across material flow paths.
• Melt Flow: At 190°C (374°F) under a 2.16 kg (4.76 lb) load, the melt flow rate is 3.3 g/10 min, indicating balanced fluidity for extrusion or molding processes.

Polymer Properties:

• Base Material: High – Density Polyethylene (HDPE)
• Modification Features:
  
  • Medium flow is suitable for efficient molding of closure components.
  • High stress – crack resistance and the slip agent ensure smooth opening and long – term sealing.

Applications:

• Beverage Industry: Specifically designed for closures of carbonated – liquid bottles to ensure air – tight seals.
• Beverage Packaging: Can be used in components of carbonated – drink packaging systems, maintaining product integrity during storage and transport.
