Lenecold is a graphene thermal interface material supplier and manufacturer based in Ningbo, China — the thermal-materials brand of NGIC, the National Graphene Innovation Center. We supply 180 W/m·K thermal pads and 1,200 W/m·K thermal plates to OEMs, cold plate manufacturers and distributors worldwide.

Who we supply
| Customer type | Typical need | What we provide |
|---|---|---|
| Server & accelerator OEMs | Lid-to-cold-plate interface in liquid-cooled racks | Die-cut pads at production volume, cycling data |
| Cold plate & heatsink manufacturers | Interface layer to bundle with the plate package | Reciprocal supply, matched to your plate flatness |
| Power electronics makers | Module-to-cooler interface for IGBT / SiC | High-temp grades, cycling qualification support |
| EV & ESS pack builders | Cell-to-cold-plate layer, large area | Large-format sheets, compression-set data |

| Distributors | Regional stock and technical support | Territory terms, training, marketing material |
Why engineers specify our material
- Solid-state. No pump-out, no dry-out, no migration — the failure modes that end grease-based designs.
- Vertically oriented graphene. Conductivity in the direction heat actually travels, not just the flattering in-plane number.
- Works at low mounting pressure. Reaches low resistance in the 10–50 psi range that real hardware delivers.
- Forgiving of gap variation. High conductivity means a thicker, more tolerant joint without a thermal penalty — which protects assembly yield.
- Backed by NGIC. Material produced within the National Graphene Innovation Center group, not brokered from the open market.
Sampling and ordering
Send your requirement
Power, footprint, gap, mounting pressure, operating temperature, target life, volume.
We recommend a grade and thickness
With the reasoning, and honest advice if a simpler material would do.
Samples cut to your footprint
Standard thicknesses ship from stock; custom dies typically within two weeks.
You test on your own hardware
We provide resistance-versus-pressure data and aging results to compare against.
Production supply
FOB Ningbo, worldwide export, with consistent batch-to-batch material.
Frequently asked
What is your minimum order quantity?
Samples have no minimum. For production, MOQ depends on whether you need standard sheet or a custom die — send your volume and we will quote.
Can you die-cut to our drawing?
Yes. Send a DXF or PDF of the footprint and we will quote tooling and piece price.
Do you work with distributors?
Yes, in selected territories. We provide technical training and marketing support alongside material supply.
Is the material electrically conductive?
Yes — graphene conducts electricity. If your interface needs dielectric isolation, tell us the voltage and we will advise on the stack-up.
What certifications do you hold?
Contact us with your specific requirement — we will provide current documentation rather than a generic list.
