Title: Molding composition of siloxane capable of extending mold lifetime

Abstract: The present invention provides the molding composition of siloxane, which is capable of extending mold lifetime where inhibitors alkene or acetylene polymerization are mixed in the molds composed of siloxane. The inhibitors can effectively inhibit the release of alkene or acetylene when a resin containing an alkene or acetylene is poured into the molds which extends lifetime of molds composed of siloxane. The inhibitors are compounds containing primarily sulfur, wherein sulfur is the most effective.
