SILTEL SG-TC4.5 THERMALLY CONDUCTIVE GAP PAD
SILTEL SG-TC4.5 Thermally Conductive Soft Silicone Gap Pad
SILTEL SG-TC4.5 is an electrically insulating thermally conductive silicone gap filler material ideal for use in electronic applications where thermal transfer over large gaps, large tolerances or creating surface contact to multiple device surfaces/heights must be achieved. Due to the specific formulation and ceramic particle filler loading, SG-TC4.5 demonstrates reliable thermal conductivity packaged with pad compliance all within a robust elastomer design.
At low pressure, it quickly begins to fill surface gaps which significantly minimizes resistance leading to efficient and reliable heat transfer.
SILTEL SG-TC4.5 is available in sheets or TIMTEL cut parts to match a wide range of industry standard or customer defined outlines.
