LDPE Resin Technologies
High-pressure low-density polyethylene (HP-LDPE or LDPE) and copolymers of LDPE with ethylene vinyl acetate (EVA) are manufactured in a high-pressure reactor. Although this manufacturing process has traditionally been higher cost and more capacity restricted than the processes used to make linear-low density polyethylene (LLDPE), improved technologies make LDPE cost competitive with LLDPE. LDPEs, with their highly branched molecular structures, offer some benefits compared to LLDPE, such as higher melt strength, which creates stability in blown film processing and in making foams, for example. LDPEs and EVAs also generally have higher clarity and sealability than LLDPE. Metallocene-catalyzed LLDPE (mLLDPE) is a competitive technology to LDPE and EVA. This processing technology creates LLDPE with better clarity and lower seal initiation temperature than conventional LLDPEs, but better physical properties than conventional LLDPE or LDPE. Metallocene-catalyzed polyolefin elastomers (mPOEs) and plastomers (mPOPs) also compete with LDPE and EVAs.
Market Drivers in the LDPE Resin Market
LDPE is used in many applications (see figure below). The largest market is film applications (e.g., bags, stretch films, packaging). Other areas include injection molded parts, extrusion coating, adhesives and sealants, and wire and cable. Metallocene-catalyzed LLDPEs compete with LDPE, and mPOEs and POPs compete with EVAs in applications including solar encapsulation. The exhibit shows key LDPE end-use applications.
