Patent ID: 8150300

Claim:
A mold which has a holding layer foamed on an inner periphery surface of a main body of a die and a releasing layer formed on an inner periphery surface of the holding layer, and is used to produce a molded body made of an elastomer, the molded body being produced by charging a liquid elastomer raw material into the inside of the mold and curing the liquid elastomer raw material, wherein (a) the releasing layer is formed of an addition two-component liquid silicone having a polysilazane-based or polysiloxane-based chain as a main chain; (b) the releasing layer contains: (i) a component which volatilizes at a curing temperature of a liquid elastomer raw material, and (ii) silica (SiO 2 ); (c) the releasing layer contains 0.5% mass or less of the component which volatilizes at a curing temperature of the liquid elastomer raw material; and (d) the releasing layer contains 1% mass or less of the silica.
