Non-Corrosive Durable Thermal Grease Paste 1.0 W/mK Long Life Silicone for CPU GPU Heat Sink Cooling

Non-Corrosive Durable Thermal Grease Paste 1.0 W/mK — Long Life Silicone Heat Sink Compound

This premium 1.0 W/m·K thermal grease paste is formulated with a high-purity silicone base for CPU, GPU and power module heat sink cooling. It is non-corrosive to aluminum, copper and electronic substrates, and delivers long service life with stable thermal performance year after year — a durable thermal compound designed to reduce rework and maintenance costs.

Why Choose This Thermal Grease Paste

• Non-Corrosive Formula — Safe for aluminum, copper, nickel and sensitive electronic components, preventing galvanic corrosion and long-term surface damage.
• Long Service Life / Durability — A non-curing silicone paste that maintains a stable paste state under thermal cycling, resisting dry-out, pump-out and hardening for long-term stability.
• Low Thermal Resistance — Excellent surface wetting and high conformity fill micro gaps between the chip and heat sink, transferring heat efficiently for extreme heat dissipation.
• High Purity Silicone Base — Low oil bleed (<= 0.3%) and low volatility (<= 0.6%), keeping the interface clean and stable over time.
• Reliable Wide Temperature Range — Performs from -40°C to 180°C without solidifying, suitable for continuous duty electronics.

Recommended Applications

• CPU and GPU cooling for desktop, notebook and server platforms
• Power modules, IGBT and MOSFET heat sink interface
• LED drivers, power supplies and switching electronics
• Automotive and EV electronics thermal management
