Rubber drying out ??
Rubber drying out ??
(OP)
My Rubber Lining Company has recently been asked to line some road tankers to be used for transport of various different corrosive liquids. Rubber will be Hypalon.
During discussions with a very experienced Tanker User he said that it is normal practice that when tankers are laid up it is usual to fill them with water to stop the rubber "drying out and degrading".
Please have any of you anny comments on this one ??
Thanks in advance, David Whitlock.

RE: Rubber drying out ??
The possible mechanisms for degradation of the rubber could be either oxidation, or attack from fumes/residues left in the tank.
I assume therefore that the reason for filling the tank with water is to prevent the build up of fumes and/or to keep oxygen away from the lining.
Maybe a someone with a chemical or process enginering background would be able to give some more insight into this question.

Tom

There may be other rubber compounds that would be more suitable than hypalon. NBR is known for having exceptional fuel and oil resistance and normally is less expensive than hypalon.
