Abstract
Disclosed herein is a novel approach to producing a seal. The seal is produced of a much lighter material than has been used before, produced by a process of mixing a compound containing uncured silicone and a volume of microspheres, and then dispensing this material into a mold. Such a mold will normally be a female mold having the negative three dimensional shape of the seal to be produced. The seal may then be pressurized and/or heated during the curing process either prior to removing the seal from the mold or after removing the seal from the mold.
