Silicone-free Thermal Gap Fillers are used whenever the volatile components of silicone endanger the function of an application. For example, in switches, relays and similar contacts on which the silicone vapors can settle and have an insulating effect. In automotive manufacturing, silicone outgassing can prevent optimum adhesion of the paint. Our silicone-free gap filler enables good thermal transfer in electronic components, even across large gaps, for example where there are different stack up heights or big tolerances. Formulation and filling of the material enable a high thermal conductivity of 1.5 W/mK. Thanks to the extreme softness and form-fitting ability of the TPE polymer, optimum thermal contact is achieved even at very low pressure. This minimizes the total thermal transfer resistance and has a shock absorbing effect. Due to its natural tackiness the material allows for an easy and reliable pre-assembly.
