LyondellBasell Lupolen 5261 ZS HDPE Resin

Physical Properties

• Density: The density of Lupolen 5261 ZS is 0.951 g/cc (0.0344 lb/in³), which is slightly different from similar grades and can impact its performance in packaging hazardous materials.
• Water Absorption: Water absorption is 0.010 %, which is crucial for maintaining the integrity of containers and preventing water – related issues with the stored substances.
• Moisture Absorption at Equilibrium: At 0.010 %, the moisture absorption at equilibrium ensures dimensional stability and consistent performance over time.
• High Load Melt Index: At 21.6 kg and 190 °C (47.6 lb and 374 °F), the 0.10 g/10 min high – load melt index shows its blow – molding processing behavior.

Polymer Properties:

• Base Material: High – Density Polyethylene (HDPE)
• Modification Features:
  
  • High viscosity for blow molding like 5261 Z, with improved stress – crack resistance.
  • Retains good shock resistance and stackability for reliable packaging.

Applications:

Lupolen 5261 ZS is primarily used for creating robust, safe containers that must perform reliably under demanding conditions. Its key applications include:

• Drums and Jerry Cans: The resin is explicitly recommended for manufacturing open-top drums and jerry cans, particularly for the packaging of dangerous goods. 
• Industrial Packaging: The material’s excellent chemical resistance and high ESCR make it a top choice for a wide variety of industrial packaging, especially for storing and transporting liquids, solids, and powders that may be corrosive or otherwise aggressive.
