Graphite sheets

Lateral heat spreading across an unusually wide operating temperature window, with general resistance to chemicals, oil and water.

Artificial graphite sheet

Artificial graphite sheet

High in-plane conductivity in thin formats for notebooks, CPU and memory modules, graphics cards and industrial hardware. Also available as PGS film from premium precursor for defense and telecom work, where rigidity and temperature range matter more than flexibility.

  • High in-plane conductivity
  • 17–70 µm standard range
  • −55 to +400 °C
  • PGS film available for defense and telecom

Flexible graphite sheet

Flexible graphite sheet

A thicker, more compliant format for consumer devices and EV battery packs, where the sheet has to follow a curved or uneven surface and keep working through vibration and thermal cycling.

  • Thicker, compliant format
  • 137–280 µm standard range
  • −55 to +400 °C
  • Smartphones, foldables, EV battery and BMS

Made, not bought

Graphite and graphene sheet is produced by our manufacturing partner on lines they built and operate, from graphene they make themselves rather than buy on the open market. That matters less for a datasheet than it does for a supply conversation — raw material availability is not a third-party dependency in this chain.

How we are set up

Send us the hot spot.
We will send back material.

Tell us the power, the envelope, the mounting pressure and what you run today. We cut evaluation parts to your geometry and give your team the data to bench them against the incumbent.
