Standard or custom gap filler

As a supplier of thermally conductive products (TCP) you will also find an extensive selection of standard or customer-specific gap fillers in various designs in our product portfolio. Gap fillers are ideal for bridging small, medium and large distances between the components and the heat sink.

Thermally conductive gap fillers for many applications

As a supplier of gap fillers, we can offer you both standard and customer-specific guide pads in various designs and, on request, also in individual shapes. These thermal pads are used for heat dissipation in electronic components and are used, for example, in LED technology, in audio and video equipment, medical devices or in the automotive sector. The aim is to eliminate air gaps between hot components and heat sinks. Our thermal pads are characterized by high quality and optimal thermal conductivity.

Gap Filler in different thicknesses

Utilization of heat conductive pads for heat dissipation

Thermally conductive gap fillers, so-called thermal gap pads, offer not only very good thermal properties, but also the possibility of compensating for small, medium or large distances between the components (hot spots) and the heat sinks, thus minimizing thermal resistance. The thermal pads act as a thermal connection between the heat sink and the respective components and thus ensure optimum heat dissipation even with larger component spacings. This protects the components from overheating.

Technical variants of our gap fillers

We supply our gap fillers in various versions, depending on the customer's requirements. Customers can choose between different thermal conductivities from 1.0 W/m*K up to 8.0 W/m*K. Our thermal pads are self-adhesive on both sides ex works. This eliminates the need for double-sided adhesive tape for pre-assembly during production. On request, our gap fillers are also available in other adhesive variants.


0 - 0,50 mm +/- 0,05 mm
0,60 - 15 mm +/- 10 %
0 - 50 mm +/- 0,5 mm
> 50 mm +/- 1,0 mm

Thermal pads in customer-specific design

We supply the gap fillers as standard plates in various thicknesses from 0.5 - 5.0 mm. Due to our many years of experience as a supplier of heat conductive pads, we can also supply you with conductive pads in your desired shapes and sizes as individual stamped parts. We would be pleased to advise you in a personal conversation.

Gap filler also available in silicone-free version (NEW 2019)

Recently we offer the heat conducting product 1K Gap Filler in silicone-free design (dispensable one-component Gap Filler) in our TCTP series, see below or here: 1K/2K Gap Filler. Also new in our range is the TCGF series of gap pads in silicone-free design, see below and under Gap Pads.

1K gap filler in silicone-free version (TCTP series silicone-free)

mtc's 1K Gap Filler is a silicone-free, high performance, thermally conductive mass that does not dry out. It has a low viscosity for easy and clean application and can be used for applications with automatic dispensers. The one-component Gap Filler is halogen-free and provides additional safety in applications where hazardous substances are prohibited.

Features 1K Gap Filler in silicone-free version
  • silicone-free
  • suitable for automatic dosing
  • easy to use, never dries out
  • good compressibility
  • natural stickiness and low contact resistance

Gap Pads in silicone-free design (TCGF series)

In addition to excellent thermal properties, gap pads also offer the possibility of compensating for small, medium and large gaps and tolerances between the component (hot spot) and the cooling unit. The basic material of the silicone-free Gap Pads is acrylic. It is naturally sticky and easy to work with.

Features Gap Pads in silicone-free design
  • naturally sticky for easy application
  • low thermal resistance at low pressure
  • silicone-free and not oil-bleeding
