POWERSIL® 190 MH

POWERSIL® 190 MH is a 1-component, ready to use, peroxide curing silicone rubber compound that is designed specifically for use in high voltage applications. Insulators extruded and molded from POWERSIL® 190 MH possess excellent resistance to arcing and tracking, increasing the reliability and reducing power interruptions.


Properties

  • good extrusion qualities
  • very good arc resistance
  • suitable dielectric properties
  • good mechanical properties
  • offers good weathering resistance

Specific features of POWERSIL® 190 MH

  • Excellent hydrophobicity behavior
  • Resistant to tracking and erosion





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.
