Abstract

A foam material is provided that is formed from a body of silicone having a cellular structure formed by a plurality of interconnected voids. The voids have a relatively high volume of between about 0.06545 to about 268.0832 mm³ and more typically about 65.45 to about 179.5948 mm³. The foam material displays unique tactile properties.
