Silicone free gap filler


Often contact surfaces between electronic components and cooling elements or housings appear to be almost flat and smooth. In reality, however, there is a rule that when contacting two flat surfaces with each other, the effective contact area (without any mechanical reworking) is only 2 to 5 percent. Specifically for minimising thermal contact resistance, Fischer Elektronik has expanded its product portfolio of thermal interface material to include silicone-free gap filler. The different variants of the GEL F 15 … product group have very good thermal properties and are particularly suitable for silicone-free applications. In terms of compressibility and excellent shape adjustments, the specific properties of the GEL F 15 material bring about full and permanent filling of the induced tolerances, varying component heights and expansion coefficients in the air gaps that are produced. The natural self-adhesion of the material also allows for easy pre-assembly and residue-free dismantling. Initially, the silicone-free, UL 94 V-0 specified gap fillers will be available for 1.0, 1.5 and 2.0 mm material thicknesses with/without fibreglass reinforcement. Blanks, cut-outs and modifications are carried out according to customer specifications in our own film punching works.


The product specialists at Fischer Elektronik will be happy to assist you with any queries you may have or any additional information you require.
