Sil-Pad
®
2000
Higher Performance, High Reliability Insulator
Features and Benefits
• Thermal impedance:
0.38°C-in2/W (@50 psi)
• Optimal heat transfer
• High thermal conductivity: 3.5 W/m-K
Sil-Pad 2000 is a high performance, thermally
conductive insulator designed for demanding
aerospace and commercial applications.
Sil-Pad 2000 is a silicone elastomer formulated
to maximize the thermal and dielectric
performance of the filler/binder matrix.The
result is a grease-free, conformable material
capable of meeting or exceeding the thermal
and electrical requirements of high-reliability
electronic packaging applications.
