I have nothing specific but I seem to remember coming across rubber lubricant in the past. It may have been with respect to sleeving on military or industrial cables but I would need to research for details. I have experimented with glycerine on surface rubber (notably part of double glazed windows which tends to crack in time) It appeared to soften them but I have not looked in depth.
