Abstract:

The report covers an evaluation of the potential for end-item applications of several elastomers purported to be both inherently ozone resistant and serviceable at temperatures as low as -65F. Using specification requirements detailed in Specifications MIL-I-3930C and MIL-R-14328A as guidelines, results of physical testing and compound development studies on ethylene-propylene, modified butyl, and propylene oxide elastomers are compared with results obtained on a compound of SB-R 1023. Although the latter is not an inherently ozone-resistant rubber, it is acceptable for use at -65F. Other physical characteristics such as heat, oxygen, water and weather resistance, deemed essential for satisfactory performance in general-purpose applications, were determined for these elastomers and are analyzed and discussed.
