Because of its outstanding UV stability, thermal stability, hot air-aging, ozone and excellent polar fluid resistance, EPDM rubber is the material of choice for manufacturers of various automotive rubber parts, including weatherstrip.
Dow’s new Advanced Molecular Catalyst and polymerization process technology advancements enable the tailored design of unique EPDM molecular architectures, including composition and molecular weight distributions.
These unique microstructural features enable Nordel-brand EPDM end-users to develop formulations that meet both process requirements and finished product specifications in many automotive applications.
This report summarizes new Nordel EPDM product developments for dense weatherstrip applications; an efficient Design of Experiment-based formulation approach for developing compounds with balanced processability and physical properties; and Nordel EPDM technical solutions for automotive dense weatherstrip applications.
