Dowsil 340 Silicone Thermal Conductive Silicone Grease

Product Attributes​​
Dowsil 340 is a white, non-curing, and non-flowing thermally conductive compound developed by Dow Corning. It is designed to provide efficient thermal management for electronic devices by ensuring effective heat transfer from components to heat sinks.

Product Description​​
Dowsil 340 is a grease-like silicone material that is heavily filled with heat-conductive metal oxides. This unique composition ensures high thermal conductivity, low bleed, and excellent high-temperature stability. The compound maintains its consistency at temperatures up to 177°C (350°F), providing a reliable seal between electrical/electronic devices and heat sinks or chassis. This enhances heat transfer efficiency, which is crucial for the performance and longevity of sensitive circuits and components in modern electronic applications.

Special Product Attributes​​
One of the standout features of Dowsil 340 is its ability to resist changes in consistency at high temperatures, ensuring a stable thermal interface over time. Its low surface tension allows it to wet most surfaces effectively, reducing thermal contact resistance and improving heat transfer. Additionally, Dowsil 340 is resistant to ozone and ultraviolet degradation, offering good chemical stability and long-term protection for electronic components. It also functions as a durable dielectric insulation and a barrier against environmental contaminants, making it a versatile solution for thermal management in demanding environments.
