Chevron Phillips Marlex 4538A LDPE Resin

Physical Properties

• Density: Tested per ASTM D1505, the density is 0.925 g/cc (0.0334 lb/in³), offering balanced properties for pharmaceutical and industrial blow molding applications.
• Melt Flow: As per ASTM D1238, at 190 °C (374 °F) under 2.16 kg (4.76 lb), the melt flow rate is 2.0 g/10 min, ensuring stable parison control in blow molding.

Polymer Properties:

• Base Material: LDPE Homopolymer
• Modification Features:
  
  • Features high melt strength and stability for complex blow molding and extrusion.
  • Offers low taste/odor and clarity, suitable for food and pharmaceutical packaging.
  • Enhanced impact resistance for durable industrial bottles.

Applications:

Marlex® 4538A is versatile across multiple sectors, particularly in blow molding for containers and flexible items.

Its applications are supported by the resin’s mechanical and thermal data, ensuring reliability and compliance.

1. Pharmaceutical and Personal Care Bottles
   • This resin is widely used for blow-molded pharmaceutical bottles and personal care containers, such as those for lotions, shampoos, and toiletries.
2. Squeezable Bottles for Food, Beverages, and Household Products
   • Ideal for squeezable bottles in food (e.g., condiments), beverages, and household cleaners, high elongation allow repeated squeezing without permanent deformation. 
3. Flexible Toys and Consumer Goods
   • For blow-molded flexible toys and adhesives packaging, the resin’s Shore D hardness of 56 and impact toughness ensure safety and durability in child-friendly products.
4. Blends and Specialty Uses
   • In blends for wood-plastic composites or to improve friction values and part flexibility, the resin’s mechanical properties like tensile yield strength and elongation integrate well, enhancing overall composite performance without compromising processability.
