Flextein S22


Flextein S22 is a thermally conductive silicone gel pad with a good combination of high thermal conductivity and compressibility. This soft gel pad provides reduced interfacial thermal resistance, along with shock absorption and ease of use. It’s unique silicone and filler combination has extremely low silicone extractables compared to many other silicone interface products. It is ideal for use to fill gaps between high-power, heat-generating components and related heat sinks, boards or chassis.
