Application Details

POWERSIL® 310 MH is the silicone rubber of choice for the manufacture all types of electrical insulating equipment for outdoor use, e.g. composite insulators, arrester housings, bushings etc.

Processing

POWERSIL® 310 MH can be processed using injection molding, transfer or compression molding. For detailed information please refer to our brochure "Solid and Liquid Silicone Rubber, Material and Processing Guidlines". To achieve a good bond between typically-used materials for electrical insulation equipment and POWERSIL® 310 MH the primer G 3243 should be used.
