i would like to get some information about heat and oil resistance cable (class 43,UL VW-1).we have been using nitrile rubber(%33 ACN)and totm plasticizer in related pvc compound but we have seen some problems about aging testing.
It is quite obvious from your posts that you have a very strong background in the chemistry of polymers and I am not sure we have many members with similar backgrounds and experience. For instance, I am a mechanical engineer and not a chemical engineer.
Your post is very specific and it may take a period of time for you to get an answer. Am I correct however in assuming you are referring to a pvc-rubber elastomeric alloy of your own design?
I have already asked a member of the staff at the WAI offices in Connecticut if we have a volunteer polymer engineer or polymer chemist as a technical advisor somewhere in the world who can properly address your query.
We will therefore just have to wait and see if we get an answer.
