Overview
Heat sink compounds or thermal greases, are wide-temperature, grease-like materials that are used to conduct thermal energy away from sensitive components to larger ventilated areas or to heat measuring and controlling instruments. The plasticity of the heat sink compound or thermal grease, allows it to readily fill gaps or voids between conducting surfaces.
Nye offers both silicone grease and non-silicone grease in our thermal grease product lines. Non-silicone heat sink compounds may be preferred, for example, when the low surface tension of a silicone grease may impact such operations as soldering and painting.

Quality rolling element bearing greases function over a wide temperature range; offer thermooxidative stability and low volatility; and have base oils that retain the viscosity needed to provide an adequate lubricant film throughout a specified range of operating temperatures, speeds and loads. Using these general characteristics as the yardstick for selecting a lubricant will help ensure high performance and long life for rolling element bearing applications.

| Nye Thermal Coupling Compounds | Operating Temperature (°C) | Thermal Conductivity (W/m°K) | Technical Notes |
| TCC 941 | -55 to 205 | 1.2 @ 36°C | TCC 941 is a water-cleanable, silicone thermal grease. It offers high thermal conductivity and virtually no bleed at elevated temperatures. It does not harden, dry out or melt after 1,000 hours at 200°C. An effective thermal couplant, TCC 941 is an excellent joint compound for any device where efficient cooling is desired. |
| TCC 942 | -40 to 210 | 2.2 @ 55°C | TCC 942 is non-silicone, synthetic thixotropic thermal grease. It will flow under moderate shear, but exhibits “no creep” features when pressure is removed, even at temperatures in excess of 100°C. As a solid it will withstand temperatures in excess of 200°C. It does not phase separate. |
| TCC 943 | -40 to 200 | 1.4 @ 50°C | TCC 943 is a non-silicone, synthetic thermal grease. It is a soft, pumpable gel that cures to a non-flowing tacky solid when heated (usually within 1 hour @ 100 to 110°C). Thermal transfer efficiency increases with cure. TCC 943 does not contribute to solder bath contamination, exhibits very low bleed and evaporation, and has excellent thermal resistance over a wide temperature range. |
| TCC 944 | -40 to 150 | 1.3 @ 50°C | TCC 944 is a water-cleanable, non-silicone, synthetic thermal grease. It has a soft, grease consistency, excellent dielectric properties, and exhibits thixotropic behavior. It is competitively priced with Dow Corning 340, but requires no solvents for clean up. |
