Dow Dowsil 340 Heat Sink Compound - 5.0 oz

DowSil 340 Heat Sink Compound
1446622

DowSil (formerly Dow Corning) 340 Heat Sink Compound is a grease-like, silicone material, heavily filled with heat-conductive metal oxides. This combination promotes high thermal conductivity, low bleed and high-temperature stability. The compounds are designed to maintain a positive heat sink seal to improve heat transfer from the electrical/electronic device to the heat sink or chassis, thereby increasing the overall efficiency of the device. Electronic devices are continually designed to deliver higher performance. Especially in the area of consumer electronics, there is also a continual trend towards smaller, more compact designs.

In combination these factors typically mean that more heat is generated in the device. Thermal management of electronic devices is a primary concern of design engineers. A cooler device allows for more efficient operation and better reliability over the life of the device.

As such, thermally conductive compounds play an integral role here. Thermally conductive materials act as a thermal bridge to remove heat from a heat source (device) to the ambient via a heat transfer media (i.e. heat sink). These materials have properties such as low thermal resistance, high thermal conductivity, and can achieve thin Bond Line Thicknesses (BLTs)which can help to improve the transfer of heat away from the device.

Applications:

• Dow Corning 340 Heat Sink Compound is suitable for thermal coupling of electrical/electronic devices to heat sinks
• Also suitable for aircraft engines where heat sink properties are required
