Why the Mould making silicone rubber mold appear with weak tear strength?

When making silicone rubber mold, some customer add a lot of silicone oil to reduce the viscosity of silicone rubber. In fact, this has the opposite effect. The tension and tear strength will be reduced badly with the addition of silicone oil, which leading to the weak and flimsy condition of silicone rubber molds.
