Standard Films: Keratherm Green

Keratherm Green is a silicone elastomer films filled with aluminum oxide which is characterized by its excellent electrical characteristics. It exhibits good thermal behaviour. Optional fiberglass reinforcement leads to very good mechanical properties. These film types posess excellent mechanical stability along with good perforation strength. Because of its structure, Keratherm Green has very good self-adhesive properties. Adhesive coatings are optionally available.

Possible Thickness: 0.125mm - 0.500mm

Applications

  • automotive
  • telecommunication units
  • DC-DC converters
  • high voltage units
