Claim:
1. A method of making a dry silicone gel comprising: providing a first set of components comprising: (1) a base polymer having a vinyl- silicone group, and (2) an addition cure catalyst; providing a second set of components comprising: (1) a crosslinker having three or four Si-H groups, (2) a chain extender having two Si-H groups, and (3) additional base polymer having a vinyl-silicone group; and mixing the first and second set of components together to form the dry silicone gel, wherein the dry silicone gel has a hardness between 100 g and 300 g, and a mole fraction of hydride present as crosslinker between 0.2 and 0.5, wherein the base polymer and additional base polymer are each a vinyl-terminated polydimethylsiloxane each having a molecular weight between 28,000 g/mol and 70,000 g/mol.
