Abstract:

Polytrifluoropropyl methyl siloxane a fluorosilicone elastomer, the material used as a dynamic seal in the LANCE propulsion unit, was heat-aged for five years at 150 to 160 F. Physical and mechanical properties were monitored through this evaluation and it was found that the elastomer had lost 70 of its tensile strength. Thus, it was evident that this elastomer was temperature-sensitive and should be monitored when used in critical applications. Author
