Abstract

Methods and systems are provided for a dry silicone gel in a closure or interconnect system. The dry silicone gel may be made by reacting a crosslinker, a chain extender, and a vinyl-terminated polydimethylsiloxane. The reaction may be conducted in the presence of a catalyst. In certain embodiments, the dry silicone gel may comprise: (1) a hardness between 100 g and 300 g, (2) a stress relaxation between 30% and 60% when subjected to a deformation of 50% of the original size of the gel, (3) a compression set between 4% and 20% after 50% strain has been applied to the gel for 1000 hours at 70° C., and/or (4) less than 10% oil bleed out under compression of 1.2 atm after 60 days at 60° C.
