SK-1350 GF Thermal Gap Filler(導熱凝膠)
Blue / Two Part Silicone-based / Thermally Conductive Gap Filler

INTRODUCTION         SK-1350 GF Thermal gap filler is a two part liquid silicone-based material, curing at room temperature once mixed. SK-1350 GF is a soft and compressible material designed to dissipate heat from electronic devices such as PCB modules by conducting it to a heat sink such as an aluminum housing.

Unlike cured thermal pad materials, SK-1350 GF thermal gap filler is supplied as a      two-part liquid component kits. When the liquid components are thoroughly mixed either by weight or volume, the mixture cures to a soft elastomer. These elastomers cure without exotherm at a constant rate regardless of sectional thickness or degree of confinement. SK-1350 GF has long term performance stability during temperature cycling up to 200℃.

SK-1350 GF thermal gap filler is used for smartphones, portable computing devices, LED lighting modules, PCB modules, communication equipment and electric vehicle parts, provide a reliable cooling solution.
