NOTES:
1. Specific Gravity can be interpreted in terms of grams per cubic centimeter.
2. Thermal Conductivity is the amount of heat in BATU per hour per square foot for a temperature gradient of one degree Fahrenheit per inch thickness.
3. The coefficient of linear thermal expansion is the change per length per degree F. The expansion of all rubbers is about the same order of magnitude, approximately 10 times that of steel. Thermal contraction may also be calculated using the coefficients to determine the shrinkage at low temperatures.
