To ensure rubber products maintain their original properties, storage conditions must be
controlled. Where practicable, ensure rubber products are:
1. kept sealed in their original packing which should be opaque;
2. kept away from direct sunlight;
3. kept away from electrical machinery -e.g. motors and generators;
4. kept in a cool, dry environment between 15° C to 25° C;
5. stored away from exhaust fumes;
6. stored separately from chemicals and fuels;
7. stored loosely packed;
8. rotated on a first in - first out basis.
Storage life for different types of rubber stored under recommended conditions are as
indicated in Table 1.2.5-1.
NOTE
:
AT 15°C THE STORAGE LIFE WILL BE ABOUT DOUBLE AND AT 35 °C ABOUT HALF OF THAT
