BLUESIL Paste 340 – Thermally conductive silicone paste for heat dissipation.
BLUESIL Paste 340 is a thermally conductive silicone paste designed for efficient heat transfer between electronic components and heat sinks. The paste fills microscopic surface irregularities and ensures better thermal conductivity than direct metal-to-metal contact.
Typical applications
- Thermal paste for CPU/GPU heat sinks and power electronics
- Thermal interface material (TIM) between the electronic component and the heat sink
- Heat Dissipation in Transformers and Motors

Frequently Asked Questions About BLUESIL Paste 340
Frequently Asked Questions About BLUESIL Paste 340.
Silicone-based greases and pastes are significantly more thermally stable (up to +200°C vs. ~150°C for mineral oil), chemically inert, hydrophobic, and do not form resins as they age. However, they are more expensive. They are suitable for applications where long-term performance is required under extreme temperatures or in chemically aggressive environments.
No. Silicone greases should never be mixed with mineral oil-based or synthetic greases. The thickening agents are different, and mixing them can cause clumping or reduce lubricating performance. Clean the system thoroughly before switching.
Store in unopened original packaging at 2–40°C for up to 36–60 months. Silicone greases remain stable for a long time even after opening, provided the container remains tightly sealed.
