4.2W Thermally conductive pad

4.2W thermally coductive pad is a composite material developed by blending methyl vinyl silicone rubber with thermally conductive ceramic fillers at a specific ratio, catering to heat dissipation devices with high thermal conductivity demands.
It delivers outstanding thermal conduction and gap-filling performance, low thermal resistance, exceptional softness and double-sided self-adhesion.
It fills air gaps between heat-generating components and heat sinks or metal housings to realize optimal heat transfer and dissipation.

Color: Khaki
Thickness: 0.5–6.0 mm
Temperature Resistance: -40°C ~ +200°C
