Abstract
Provided is a method of stabilizing an elastomeric property of an elastomeric material. The method includes placing the elastomeric material in a pressurizing chamber and applying a suitable hydrostatic pressure to the elastomeric material within the pressurizing chamber to at least partially compress the elastomeric material. Application of the hydrostatic pressure is maintained for a period of time suitable to at least partially stabilize a restorative force exhibited by the elastomeric material in response to subsequent exposures of the elastomeric material to a compressive force.
