2.5w/m-K Interface Pad Heat Transfer Materials

TP250 series thermal pad is naturally sticky silicone based insulation conductive material which is used to fill air gaps between heat generating components and heat sinks.

Due to its low hardness and great compressibility, TP250 thermal pad works as the perfect gap filler and bridges uneven surface and gaps without any problems.
It can replace Fujipoly GR25A , Laird Tflex500, Bergquist GP2500 ,Denka FSL-BS.

TP250 series thermal pad main features:

Thermal conductivity: 2.5 W/m-K

Extremely soft and cost effective

Naturally tacky for easy assembly

Electrically insulating

TP250 series thermal pad typical applications:

LED lighting

Power conversion / supply

Thermal module

Electric vehicle battery

Semiconductor, IC, CPU.MOS and heatsink

Area where heat needs to be transferred to a frame, chassis, or other type of heat spreader
