Why do silicone molds exhibit poor tensile strength

Because customers add a large amount of silicone oil to the silicone gel in order to reduce its viscosity and make it easy to operate during the mold production process,cake mould making silicone this will make the silicone gel very soft, candle making silicone resulting in poor tensile resistance, reduced tear strength, and decreased tensile strength, resulting in the mold being not durable, with short service life, and fewer mold turns.
