SIL-PADK10 304X304 SHEET

## **Sil-Pad® K-10** 

The High Performance Kapton[®] -Based Insulator 

## **Features and Benefits** 

- Thermal impedance: 

- 0.41°C-in[2] /W (@50 psi) 

- Tough dielectric barrier against cut-through 

- High performance film 

- Designed to replace ceramic insulators 

Sil-Pad K-10 is a high performance insulator. It combines special film with a filled silicone rubber. The result is a product with good cut-through properties and excellent thermal performance. 

Sil-Pad K-10 is designed to replace ceramic insulators such as Beryllium Oxide, Boron Nitride, and Alumina. Ceramic insulators are expensive and they break easily. Sil-Pad K-10 eliminates breakage and costs much less than ceramics.
