Chemplex 1381 Thermally Conductive Heat Sink Silicone Compound
General Description:
Chemplex 1381 Heat Sink compound is a silicone fluid based, grease-like material specially blended with fine thermally conductive metal oxide powders. Formulation results in very high thermal conductivity, low bleed and excellent high temperature stability. This highly viscous product will not harden, melt or dry out and will tenaciously adhere to metal surfaces even when exposed to high temperatures for extended periods of time. Meets Mil-Spec MIL-C-47113.
Applications:
Chemplex 1381 removes or transfers heat from one area to another. It is used on transistors, diodes, rectifiers and transformers in the electronic industry. This is an excellent general purpose thermally conductive compound.
