Standard Films: Keratherm Brown

Keratherm Brown represents a well-balanced ratio of cost-effective solution and very good thermal properties. These fiberglass reinforced films along with their very smooth surface exhibit very good thermal resistance properties with a high insulation capacity at low mounting pressures.

Possible Thickness: 0.250mm - 0.500mm

Applications

  • automotive
  • white goods
  • engine controllers
  • audio and video components
  • LCD displays
  • power converters (AC-DC, DC-DC)
