PROPERTIES OF RUBBER
A: Due to the great number of existing chemicals, possible temperatures and times of exposure, the stated qualities can vary from case to case.
B: The qualities of the rubber become worse at relatively high or low temperatures.
C: The stated ranges are accurate under normal circumstances. Extreme strains or environments will make the actual ranges smaller.

++ = Perfect or very good.
+ = Good.
0 = Average qualities.
- = Poor qualities.
