LDPE (ExxonMobil)

        LDPE resins

        The flexibility of ExxonMobil Chemical’s low density polyethylene (LDPE) resin technology allows us to produce an extensive grade slate, ranging from homopolymers to high density grades.

        These LDPE resins offer manufacturers low production costs for a wide range of products with different levels of strength, stretch, clarity and puncture resistance. With this grade slate, manufacturers

 can produce films for thousands of applications, including:
         Blown and cast film
         Extrusion and coating
         Rotational and injection molding

        LDPE resin grades are branched polyethylenes, which provide easier processing, higher melt strength

and superior optical properties compared with linear polyethylenes. The very-low-haze grades provide excellent optical properties. The branched structure of LDPE also makes it ideal to serve as the main

resin component in shrink film structures.

        These attributes of LDPE resins are often exploited in synergistic blends. For example, the addition

 of 5% to 10% LDPE to Exceed™ mPE resins1 significantly improves the processability and clarity of

Exceed mPE, while the addition of 20% to 30% Exceed mPE resins to LDPE resins greatly improves

melt strength.

        The LDPE resins cover general-purpose and high-performance film applications. ExxonMobil

Chemical currently has among the highest-density LDPE resin grades available in the market.

These grades are especially suited to applications such as over-wrap, where a combination of

high stiffness and clarity is required.
