SIL PAD TSP 1800ST

**Sil-Pad® 1500ST** 

Electrically Insulating,Thermally Conductive, Soft Tack Elastomeric Material 

## **Features and Benefits** 

- Thermal impedance: 

- 0.23°C-in[2] /W (@50 psi) 

- Naturally tacky on both sides 

- Pad is repositionable 

- Excellent thermal performance 

- Auto-placement and dispensable 

Bergquist Sil-Pad 1500ST (Soft Tack) is a fiberglass reinforced thermal interface material that is naturally tacky on both sides. Sil-Pad 1500ST exhibits superior thermal performance when compared to the competitors’ thermal interface materials. Sil-Pad 1500ST is supplied in sheet or roll form for exceptional auto-dispensing and auto-placement in high volume assemblies. Sil-Pad 1500ST is intended for placement between an electronic power device and its heat sink.
