Polar Sil-Pad is a composite of Silicon rubber and fiberglass. The material is specially formulated for use as a thermally conductive insulator.
| Key Features |
Benefits |
- Surfaces are pliable and allow complete surface contact with excellent heat dissipation. The reinforcing fiberglass provides excellent cut-through resistance.
|
- Thermal impedance 1.13oC-in2/W(@50 psi)
- Excellent mechanical and physical characteristics.
- Flame retardant
