Dow Corning 340 Silicone Heat Sink Compound
Dow Corning 340 Silicone Heat Sink Compound is a silicone-based thermal interface material used to improve heat transfer between electronic components and heat sinks. The compound fills surface irregularities to reduce air gaps, helping transfer heat away from power devices efficiently. Its smooth, grease-like consistency allows uniform application across metal and ceramic surfaces, supporting stable thermal contact in electronic assemblies.
Stable Performance Across Wide Temperature Ranges
This thermal compound remains non-curing and non-melting throughout an operating range of –40 °C to +199 °C. It does not dry out or harden during long-term use or repeated thermal cycling. The formulation provides electrical insulation, making it suitable for use with semiconductors and high-voltage components where both thermal control and electrical safety are required.
Suitable for Industrial and Commercial Electronics
Dow Corning 340 is commonly used in power supplies, UPS systems, IGBT modules, rectifiers, and motor drives. Its resistance to oxidation and evaporation supports consistent thermal performance over extended periods. The compound is easy to apply, maintains its physical properties over time, and is suitable for both manufacturing and maintenance applications.
