In order to reduce the viscosity ofsilicone rubber and pursue a good quality, you may add a lot of silicone oilinto the silicon rubber when making molds. In fact, it might have just theopposite effect. The tension and the tear strength will be reduced badly withthe addition of silicon oil. And the silicon molds will be in a weak and flimsymanner.

Why is the tear strength of the siliconemold weak?
