PYROID® HT pyrolytic graphite thermal spreaders and thermal vias are a powerful new material solution in the battle against thermal heat in state-of-the-art electronic circuits and devices.
PYROID® HT pyrolytic graphite thermal spreaders and vias provides engineers high purity (>99.999%) and lightweight (2.25 g/cc) spreader options with exceptional thermal performance.
PYROID® HT matches the thermal performance of CVD diamond at 1700 W/mK and substantially better economics. Available in sheet form up to 30 cm2 and any thickness ranging from 0.25 mm to 1.3 mm, this material is ideal for high-volume production and provides economic value at the device assembly level.

Thermal Conduction Comparison
GREATER THAN 4 X COPPER AND NATURAL GRAPHITE
GREATER THAN 5 X AIN AND BeO SPEADER MATERIAL
This exciting new material offers high tensile strength and a significant increase (90 times) the flexural modulus of existing natural graphite spreader materials.
And we can engineer the Coefficient of Thermal Expansion (CTE) planes to carefully match the substrate and solder conditions to maintain the joint integrity.
Benefits of PYROID® HT Pyrolytic Graphite:
- Higher strength than alternative graphitic materials
- High thermal conduction
- Exceptionally consistent quality and performance

Resulting in:
- Significant thermal spreading
- Increased component reliability
- Significant weight savings
- Lowered component and system costs
Ideal for two and three dimensional thermal spreader applications like high-heat flux semiconductor power electronics, such as RF and wireless, LEDs, laser diodes, wide gap semiconductors, direct die attachment, and integrated circuit lids, to name a few.
What about hot spots?
For hot-spot issues, our HT standard spreader material offers maximum normal component of thermal conductivity at a cost effective solution without the need for special vias.
