The Permeability Characteristics of Silicone Rubber
imageserv5.team-logic.comCrosslink density at the level required in silicone rubber showed little effect on permeability. Filler levels reduce permeability in proportion to volume fraction [9, 10]. However, fillers also increase the specific density. The fillers in silicone rubber increase the enthalpy of the solution of
