hi all,
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.

Hello again serdar1970,

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.

Thank you for your patience.

Sincerely,

Hi peter,

I have solved this problem by using fume silica.
