Like Rolf, I would also recommend DuPont Dow Elastomer's Engage ethylene elastomer for this application. The lack of diene in Engage improves the heat, thermal, and UV resistance of the elastomer. For a calendering process, I would suggest that you evaluate a low melt index product such as Engage 8100 or Engage 8150.
