Lenecold is the thermal-materials brand of NGIC — the National Graphene Innovation Center in Ningbo, China. We manufacture vertically-oriented graphene thermal interface materials in-house, from graphene assembly through to die-cut finished parts.
Why the manufacturing route matters
Most graphene TIMs on the market are made by mixing graphene flakes randomly into a polymer matrix. Random orientation means heat has to hop between flakes through a resistive polymer — which is why many "graphene" products land at 5–15 W/m·K despite the extraordinary conductivity of graphene itself.
Our process assembles the graphene into a vertically-aligned structure before it becomes a pad, so the high-conductivity axis points the way the heat is going. That single difference is what separates 180 W/m·K from 15 W/m·K.
| Random-flake composite | Vertically-aligned graphene | |
|---|---|---|
| Graphene orientation | Random | Aligned through-plane |
| Heat path | Flake → polymer → flake | Continuous through-thickness channel |
| Typical through-plane k | 5–15 W/m·K | 180 W/m·K |
| Sensitivity to thickness | High | Low |
What we make
Capabilities for OEM and ODM buyers
Die-cutting to drawing
Any footprint, with holes, slots and notches. Supplied on release liner or in tray packaging for automated assembly.
Custom thickness and formulation
0.2–2.0 mm for pads, 0.5–10 mm for plates. Compression behaviour and hardness can be adjusted to your assembly pressure.
Surface finishes on plates
Cu-clad, Ni/Au plating, anodized — for solderable or corrosion-resistant requirements.
Validation support
ASTM D5470 test data, 150 °C × 1500 h aging results, and samples sized for your own fixture.
Export and logistics
FOB Ningbo, worldwide shipping, documentation prepared for customs and for RoHS / REACH declarations.
Who we are
NGIC — the National Graphene Innovation Center — is China's national-level graphene innovation platform, based in Ningbo. Lenecold is its thermal-materials brand, which means the material science, the pilot line and the production line sit in the same organisation. For a buyer, that translates into shorter iteration cycles on custom development and direct access to the people who made the material.
