Durability of crosslinked polydimethylsyloxanes: the case of composite insulators [PDF]
Science and Technology of Advanced Materials, 2008 Most applications of silicones are linked to their hydrophobic properties and (or) their high resistance to ageing (e.g. thermal ageing and photoageing). However, when placed in extreme environments, these materials can fail as in the case of epoxy/fiber glass composite powerlines insulators, where crosslinked polymethylsyloxanes (PDMSs) are used as ...
