Silicones for Power Electronics

Adhesive, Gel and Thermal Material Solutions

With the development of alternative energy sources to power our world, the need for power electronics is increasing.
High power conversion requires high switching frequency,

• resulting in increased junction temperatures
• that require materials that can withstand higher operating temperatures.

Silicone Solutions supplies a range of Momentive of silicone products that may be used for power electronic devices. Correct material selection is critical and Silicone Solutions are able to offer both technical support and sample materials.

Automotive Requirements For Thermally Conductive Materials

Trends leading to the increased use of power electronics

These include

• Reducing carbon dioxide emissions from systems and processes,
• Lowering a dependence on fossil fuels,
• Using energy more efficiently are trends leading to the increased use of power electronics.

HEV and EV

In the automotive industry, moving away from the traditional fuel engine has opened the door for hybrid electric vehicles (HEV) and electric vehicles (EV).

Higher Operating Temperatures

• Cost efficiency,
• Miniaturization of high performance components,
• and Multiple system integration has led to higher operating temperatures.

Temperature stability, dielectric strength and low modulus

Momentive silicones have been shown to be key enablers of this technology trend, due to temperature stability, dielectric strength and low modulus.
Momentive is developing silicone products to withstand a wider range of operating temperatures as compared to epoxies, while still providing the needed protection
for sensitive electronic components.
