Abstract
Use for increasing the longevity of moulds produced from silicone elastomer crosslinking by a polycondensation reaction, of an additive capable of stabilizing the silicone elastomer constituting the mould with respect to materials to be moulded, the additive being chosen from the group consisting of: (a) elemental sulfur; synergistic combination of (a)+(b), wherein (b) is selected from the following compounds: (b1) at least one "symmetrical" polysulfide silane, (b2) at least one thiomonopropionic acid ester, (b3) at least one thiodiproptonic acid ester, (b4) at least one poly(thiomonopropionic acid ester) connected to a tetravalent carbon atom. (b5) at least one polysulfide compound selected from (b-5/1) a poly(alkylphenolsulfide) and (b-5/2) an alkyl thiuram sulfide, and (b6) at least one phosphate.
