Disclosed are methods to maintain the durability of silicone-thermoplastic composite articles, which comprise flame-retardant thermoplastics and silicone elastomeric materials, with age by incorporating a stabilizing additive in the silicone elastomeric materials. This disclosure also provides improved silicone-thermoplastic composite articles and uses for such silicone-thermoplastic composite articles. A silicone-thermoplastic composite article comprises: (i) a thermoplastic article comprising one or more flame-retardant additives, wherein the thermoplastic article has an available surface; and (ii) a cured silicone elastomer part in direct contact with the available surface of the thermoplastic article (i). The silicone elastomer part is the cured product of a silicone elastomer composition comprising from 0.25 wt. % to a maximum of 5 wt. % of a stabilizing additive. The stabilizing additive is selected from the group consisting of magnesium carbonates, magnesium hydroxy carbonates, magnesium oxide, and mixtures thereof.
A silicone-thermoplastic composite article comprising:
A method for fabricating a silicone-thermoplastic composite article, wherein the silicone-thermoplastic composite article comprises:
A method to maintain the durability of a silicone elastomer part in physical contact with a flame-retardant thermoplastic having an available surface which silicone elastomer part in use is subjected to mechanical compression and exposed to temperatures of greater than 85° C., the method comprising the steps of:
