Shelf Life Of Uncured Protective Rubber Linings

Commercial-Grade-Rubber-Sheet

In determining the shelf life of uncured rubber linings, several instances but be understood:

  1. The level of heat memory built into a compound (ex. Synthetic Rubber takes more heat to break down than a Natural Rubber)
  2.  The lower the storage temperature, the longer the rubber lining will be useable.

As a rule of thumb the average uncured rubber linings (NR, IIR) will have a shelf life of approximate shelf life of 9 to 12 months if stored at a temperature of 10°C (also out of sunlight).  If the linings are stored at a lower temperature the rubber lining will much longer the 12 month period.  Please note that Neoprene (CR) and Nitrile (NBR) compounds have a typical shorter shelf life than the above mentioned compounds.  In dealing with these compounds a great of caution is to be used as they can cure much faster.  If storing rubber at a lower temperature that the recommended 10°C  the rubber may become frozen, if this was to happen the roll will need to be unrolled and left at an ambient temperature for 2 weeks to thaw the rubber.  After the 2 week interval the rubber will need to go on a hot table to help facilitate any shrink that might of occurred during the freezing process.
