POE Dow‑DuPont 7447
POE Dow‑DuPont 7447
POE Dow‑DuPont 7447 is an ethylene‑butene copolymer. Benefiting from high melt index and low density, it delivers excellent performance in processing flowability and product softness. In addition, it complies with food‑contact grade standards.
Main Applications
Wire‑and‑Cable Materials: High melt index provides outstanding processability, while low density endows products with favorable softness. It is well‑suited for polymer modification and blending materials for wires and cables.
Polymer Modification: Commonly used for toughening polypropylene (PP) to improve its low‑temperature impact resistance. Widely applied in automotive components such as bumpers and door panels.
Other Fields: Also applicable to packaging materials and other articles molded via injection molding, extrusion and other processes.
