ExxonMobil LD 202.48 LDPE Resin

Physical Properties

• Density: Measured by ExxonMobil Method, the density is 0.915 g/cc (0.0331 lb/in³), designed for high-speed lightweight extrusion coating to reduce material consumption.
• Melt Flow：Per ASTM D1238, MFR is 12 g/10 min at 2.16 kg load and 190 °C; high melt index boosts coating efficiency on non-woven substrates.
• Neck In：
  
  • As per ExxonMobil Method, at a constant output of 35 rpm and speed of 164 ft/min (50 m/min), the neck in measures 4.10 cm (1.61 in);
  • As per ExxonMobil Method, the neck in measures 3.60 cm (1.42 in).
• Drawdown: At constant output at 35 rpm (ExxonMobil Method), the drawdown is 4.00 m/s (787 ft/min).

Polymer Properties:

• Base Material: Low-Density Polyethylene (LDPE)
• Key Features:
  
  • Good Optical Properties: This resin is formulated to produce films with good clarity and gloss.
  • Excellent Processability: The melt index (MI) of LD 202.48 provides balanced flow characteristics.
  • High Toughness: The grade provides a robust balance of mechanical strength.

Applications:

The balanced and reliable properties of LD 202.48 make it an ideal material for a range of demanding film applications.

• General Purpose Bags: Used to produce various bags, including consumer bags, bread bags, fresh produce bags, and other general-purpose packaging.
• Food and Textile Packaging: Its balanced strength and optical properties are well-suited for films used in both food packaging and textile wrapping, offering product protection and visibility.
• Co-extrusion Films: The consistent processability and film properties make it a suitable component in multi-layer co-extrusion films where different property layers are required.
• Shrink Films: Its good mechanical properties and processability also make it a viable option for certain shrink film applications.
