18W/mK Silicone M.2 Thermal Pad – High-Performance Heat Dissipation
Keep your laptop, SSD, CPU, and LED components running cool and efficiently with this professional-grade 18W/mK Silicone Thermal Pad. Engineered from a unique Nano Silicon Grease material, it delivers exceptional thermal conductivity and electrical insulation — making it the ideal heat transfer solution for M.2 2280 SSDs, CPUs, heatsinks, and other high-output electronic components.
Made in Mainland China.
Key Features
- High Thermal Conductivity: 18W/mK coefficient ensures rapid and efficient heat transfer away from sensitive chips and components.
- Non-Conductive & Safe: Breakdown voltage of 9.8KV — fully electrically insulating so there's zero risk of shorts.
- Nano Silicon Grease Material: Specially formulated for superior thermal diffusion performance on high-heat electronic parts.
- Soft & Flexible: Low Shore hardness (55 ± 5) and excellent ductility allow the pad to conform perfectly to uneven SSD and heatsink surfaces.
- Low Viscosity: Won't damage warranty labels or leave sticky residue — easy to install and remove.
- Wide Temperature Range: Operates reliably from -40°C to 200°C for extreme-use environments.
- Durable Construction: Corrosion resistant, tear resistant, extendable, and non-toxic.
- Multiple Thickness Options: Available in 0.5 / 1.0 / 1.5 / 2.0 / 2.5 / 3.0mm to suit various build requirements.

Frequently Asked Questions
Q: What size M.2 SSD is this thermal pad compatible with?
A: This 70 x 20mm silicone thermal pad is specifically designed to fit M.2 2280 SSD heatsinks (22 x 80mm form factor), making it ideal for most standard M.2 SSDs used in laptops and desktop builds.
Q: Is this thermal pad electrically safe to use near circuit boards?
A: Yes. This pad is fully non-conductive with a breakdown voltage of 9.8KV, meaning it provides excellent electrical insulation and poses no risk of short circuits on your motherboard or SSD.
Q: What thickness should I choose for my build?
A: The correct thickness depends on the gap between your M.2 SSD and the heatsink. Common gaps are 1.0mm or 1.5mm. We recommend measuring the gap before ordering. Available options include 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0mm.
Q: Will this thermal pad damage my SSD's warranty sticker?
A: No. The low-viscosity formulation ensures the pad does not bond aggressively to the SSD surface, so it can be removed without tearing or damaging warranty labels.
