Chemplex1381 Thermally Conductive Heat Sink Silicone Grease


Chemplex 1381 Heat Sink Compound is a silicone fluid based, grease-like material specially blended with fine thermally conductive metal oxide powders resulting in very high thermal conductivity, low bleed and excellent high temp stability. Chemplex 1381 will not harden, melt, or dry out and will tenaciously adhere to metal surfaces even when exposed to high temps for extended periods of time.


When energized, many electrical/electronic devices become warm, even hot to the touch. This heat can become detrimental to the performance and life of heat sensitive electrical parts. Chemplex 1381 is commonly used as an interface to facilitate the transfer of heat from the electrical device to the heat sink or chassis. Chemplex 1381 removes or transfers heat from one area to another. Also used to even out temps from local high temp areas by conducting heat to larger, cooler areas. Use Chemplex 1381 on transistors, diodes, rectifiers and transformers in the electronic industry. If a non-silicone heat sink compound is required please ask about our Chemplex NS 2736 product.
