FUNCTIONALLY GRADIENT ELASTOMER MATERIAL FOR DOWNHOLE SEALING ELEMENT

摘要

A sealing device of enhanced configuration for use in downhole in a well. The device may include an element of elastomeric and unitary construction. At the same time, however, the element may include a substantially cured outer shell disposed about a substantially under-cured inner core. Thus, enhanced robustness and durability may be provided to the device in light of downhole conditions without sacrifice to sealable function of the device.
