Study of compatibility of FC-72 with several common packing and sealing materials

Abstract

There are some uncertainties about the compatibility of FC-72 with PI and PEEK as well as nitrile butadiene rubber(NBR), fluororubber(FKM) and silicone sealing materials. This paper provides a test platform for liquid FC-72 to carry out compatibility test with test materials. By carrying out compatibility reaction between materials and periodically recording the quality change of test materials, the compatibility between different materials and FC-72 can be determined.
