ENCAPSULANT COMPOSITION FOR USE IN SIGNAL TRANSMISSION DEVICES

摘要

The invention relates to a grease compatible, hydrolytically stable dielectric encapsulant capable of being used to encapsulate a splice of a signal conducting device comprising: an extended reaction product of an admixture of a) an effective amount of an anhydride functionalized compound having reactive anhydride sites; b) an effective amount of a crosslinking agent capable of reacting with the anhydride sites of said compound to form a cured cross-linked material; and c) an effective amount of an oxirane containing material to provide hydrolytic stability; wherein said reaction product is extended with at least one plasticizer present in the range of between 5 and 95 percent by weight of the encapsulant and said at least one plasticizer is essentially inert with said reaction product and is substantially non-exuding therefrom; and said encapsulant having a C-H adhesion value of at least 4. The compositions are useful for encapsulating signal transmission devices.
