Heat Transfer of HNBR

[gumby69]

What is the heat transfer coefficent for HNBR with modest amounts of carbon black for instance.
I would presume it would be similar to regular HNBR.
Thanks
Bill

I can't remember Bill but I do remember that heat transfer rates increase in (more or less) direct proportion with increasing volume fraction of carbon black. (Carbon black grade is relatively unimportant for this.)
