Abstract
Methods and systems are provided for a dry silicone gel. The dry silicone gel comprises a base polymer having a vinyl-silicone group, a crosslinker, and a chain extender. The dry silicone gel may be made by reacting (a) a first set of components comprising a base polymer having a vinyl-silicone group and an addition cure catalyst with (b) a second set of components comprising a crosslinker, a chain extender, and additional base polymer. In certain circumstances, the base polymer and additional base polymer are vinyl-terminated polydimethylsiloxane.
