Abstract

The stability of silicone elastomers in moist oxygen and moist oxygen-ozone atmospheres at a temperature of 238 degrees C has been found to be improved, by incorporating in the elastomers about 2% by weight of stearic acid.

Oxidation Stability of Silicone Elastomers

The stability of silicone elastomers in moist oxygen and moist oxygen-ozone atmospheres at a temperature of 238 degrees C has been found to be improved, by incorporating in the elastomers about 2% by weight of stearic acid.

The extent of oxidation, as measured by an infrared spectroscopic technique known as attenuated total reflection (ATR), was slowed down in comparison with control samples containing no stearic acid. During the test the water vapor pressure was 100mm and the ozone concentration was from 1.5 to 10 parts ppm.
