| Silopren* Electro 242-0 is a two-component liquid silicone rubber with a very high flowability especially developed for the economical production of large articles, like hollow core insulators or cable accessories. Due to its low viscosity Silopren* Electro 242-0 can be used in various casting processes if an appropriate metering and mixing equipment is available. Key Features and Benefits Vulcanisates consisting of Silopren* Electro 242-0 are distinguished by the following properties: outstanding ageing behaviour and weather resistance fast hydrophobicity transfer and hydrophobicity recovery rapid vulcanisation exellent dielectric behaviour over a wide range of temperatures very good tracking and arc resistance excellent flowability high stability and flexibility at low temperatures excellent stability to ozone and ultraviolet light not readily combustible, does not melt or drip easy pigmentable with LSR Color Pastes Potential Applications Because of the outstanding properties Silopren* Electro 242-0 is particularly suitable for the following elastomeric articles: hollow core insulators, high voltage plugs, cable connectors, fittings and terminals, suspension and long rod insulators, post line and pin insulators and surge arresters.&& |
