Chevron Phillips Marlex 1122 LDPE Resin

Physical Properties

• Density: Measured per ASTM D1505, the density is 0.920 g/cc (0.0332 lb/in³), a key factor for lightweight material applications.
• Water Vapor Transmission: At 0.0317 mm thickness (ASTM F1249), the rate is 15.5 g/m²/day, showing moderate moisture resistance.
• Oxygen Transmission Rate: At 0.0317 mm thickness (ASTM D3985), the rate is 5200 cc/m²/day, suitable for general packaging needs.
• Thickness: Tested at 31.8 microns (1.25 mil), a critical dimension for determining material performance in applications.
• Melt Flow: As per ASTM D1238, the rate is 2.1 g/10 min at 190°C under 2.16 kg, ensuring good processability.
• Antiblock/Slip Levels: Both at 0.000 ppm, indicating no added agents for anti-sticking or friction reduction.

Polymer Properties:

• Base Material: Low Density Polyethylene (LDPE)
• Modification Features:
  
  • Formulated for film applications with easy processing and no additive requirements.
  • Provides good contact clarity for transparent and visually appealing films.
  • Easy processing in blown film for cost-effective manufacturing.

Applications:

• Blown Film Packaging: Manufactures trash bags, storage liners, and masking films for household and construction use, prioritizing cost-efficiency.
• Food Storage Films: Creates clear sandwich bags and food wraps that meet FDA standards for direct food contact.
• Industrial Masking: Produces temporary protective films for painting, construction, and automotive assembly with easy removal.
