POWERSIL® 190 MH silicone rubber is a good choice for manufacturing all types of electrical insulating equipment for outdoor use, e.g. composite insulators, arresters housings, bushings etc..
More information can be found in the brochure “Solutions for the Transmission and Distribution Technology”.
POWERSIL® 190 MH is especially designed for processing by extrusion technologies. But it can also be processed by compression, transfer or injection moulding techniques. For optimal bonding of POWERSIL® 190 MH to FRP substrates the use of Primer G 3243 is recommended.
For detailed information about processing please refer to the brochure ELASTOSIL® HTV-Silicone Rubber - Processing.
Further information for storage: Store in a dry and cool place.
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
