Thermally conductive gap fillers minimize thermal resistances between electronic parts and heat sinks, such as heat plates or housings. Through their excellent compliance they fill gaps caused by tolerances, different stack up heights or different expansion coefficients entirely and on a long-term basis.

The natural self-tackiness makes them suitable for easy pre-assembly.
After use the materials can be removed without residues.

Dispensable 2-part gap fillers compensate extreme tolerances and spaces at non-coplanar systems without exerting pressure. Their thixotropic behavior allows for a definite placement and cure-in-place.

Non elastic, plastic gap fillers allow for realizing a thermal contact over big gaps and tolerances at almost zero pressure.
