LyondellBasell Lupolen 5621 D HDPE Resin

Physical Properties

• Density: The density of this grade is 0.955 g/cc (0.0345 lb/in³), which affects its mechanical and physical characteristics in container – making applications.
• Water Absorption: Water absorption is 0.010 %, which is important for maintaining the quality of products stored in the containers, especially those sensitive to moisture.
• Moisture Absorption at Equilibrium: At 0.010 %, the moisture absorption at equilibrium helps keep the material’s dimensions stable over time.
• Melt Flow: At 2.16 kg, 190 °C (4.76 lb, 374 °F), the 0.265 g/10 min melt flow rate aids container production by blow – molding.

Polymer Properties:

• Base Material: High – Density Polyethylene (HDPE)
• Modification Features:
  
  • Melt flow property provides specific processing capabilities for manufacturing containers.
  • Offers a combination of mechanical and thermal properties for various applications.

Applications:

The main applications for Lupolen 5621 D are centered around producing durable, rigid containers. These include:

• Packaging for Consumer Goods: The resin is used to make bottles for a variety of consumer products, such as laundry detergents and other household cleaners. 
• Industrial Containers: Its robust mechanical properties and good ESCR also make it suitable for manufacturing jerry cans and other containers for industrial use, where durability and resistance to chemicals are a must.
• Toys and Leisure Products: The resin’s impact resistance and rigidity also make it a reliable choice for blow-molded toys and other leisure items that need to be tough and long-lasting.
