Thermal Management > Gap Fillers
Gap fillers are soft materials designed to conduct heat away from uneven surfaces. Improved conformability allows for intimate contact over rough surfaces or multiple component heights. Gap fillers reduce air gaps and do not require thermal grease. Dramatic production cost reductions and improved product uniformity result from the use of Transtherm gap fillers. Gap filler T offers electric insulation while Gap filler E is electrically conductive. Transtherm gap fillers are available in a variety of thicknesses.
