Keratherm brown
Keratherm brown, with its very good ther-
mal properties, is an excellent choice for
cost-effective solutions. These bre glass
reinforced lms, along with their very
smooth surface, have very good thermal
resistance with a high insulation capacity at
low mounting pressures.
Applications
■ automotives
■ engine controllers
■ LCD displays
■ power converters (AC-DC, DC-DC)
■ audio and video components
■ white goods
