Thermally Conductive Low Compression Force Thermal Putty
Parker ChomericsTHERM‐A‐GAP PAD 70TP is a high performance, highly conformable thermally conductive gap filler pad with a typical thermal conductivity of 7.0 W/m‐K. It provides superior thermal performance and long‐term stability over conventional thermal pads with very low compression force. THERM‐A‐GAP PAD 70TP is designed to provide effective heat transfer between electronic components and their associated cooling features such as heat sinks. The physical properties of this gap pad allow it to exhibit very high conformability and minimize the compressive load on underlying electronics. “TP” in the product name stands for “Thermal Putty” indicating that, unlike other gap pads, this material is meant for static, one‐time assembly because it will permanently conform to displace air gaps caused by uneven surfaces or rough surface textures.
