POE Dow‑DuPont 8180
POE Dow‑DuPont 8180
POE Dow‑DuPont 8180 is a low‑density elastomer with good compatibility with polyolefins. It is especially suitable for applications requiring improved material toughness and processing flowability.
Main Applications
Mainly used for general‑purpose thermoplastic elastomers, impact modification, thermoplastic polyolefin (TPO), as well as wires and cables. For example, in the automotive industry, it is used to produce TPO components requiring excellent low‑temperature impact resistance, such as bumpers and door panels.

Processing Methods
ENGAGE™ 8180 POE is suitable for multiple processing methods including injection molding and extrusion, and it blends easily with other resins.
Blending Modification: When applied for impact modification of PP and PE, POE 8180 can omit complicated granulation or pre‑mixing procedures compared with conventional EPDM, and achieves better mixing and dispersion performance. Its excellent flow characteristics also help improve filler dispersion.
Cross‑linking: Peroxides, silanes or irradiation can be adopted for effective cross‑linking to improve heat‑aging resistance and compression set.
Wire‑and‑Cable Processing: Benefiting from its outstanding electrical properties and weather resistance, it features easy processing in wire‑and‑cable manufacturing and good miscibility with other materials.
