Formulating Advantages for Automotive Weather-strip with Nordel MG
|Date Published||June 1, 2004|
This paper provides information on Nordel MG and the DuPont Dow Elastomers TPV program. Cost and performance advantages relevant to automotive weather-strip using Nordel MG in TPV production are highlighted. Some background is provided and the Nordel MG products appropriate for production of high performance TPVs are discussed. Formulation data is presented showing the effects of changes in EPDM, filler, polypropylene and oil, and curative level on the performance of TPVs. Of particular interest for automotive weather strip, compression set can be improved by the use of Nordel MG. Carbon black also reduces the weight of the finished TPV compared to clay. Phenolic curative level is important for surface smoothness.
