Ultra-Low Thermal Resistance
Thermal resistance decreases with applied pressure
and stabilizes at as low as 0.05 ℃·cm2/W, enabling highly
efficient heat transfer under real-world operating conditions.
Excellent Compressibility
Achieves >50% compression at 50 psi, effectively
conforming to surface irregularities and mitigating thermal
bottlenecks caused by die warpage and uneven mating surfaces.
High Resilience
Recovers over 70% of its original thickness after 50%
compression, maintaining consistent interface contact and
minimizing long-term thermal resistance drift.
Zero Pump-Out
No migration or extrusion under sustained dynamic
loading — dimensional stability near zero. Eliminates
dry-out and void formation common in traditional thermal greases.
Proven Long-Term Reliability
Thermal resistance increase ≤5% after rigorous environmental aging:
1000 hours at 125°C (High-Temperature Storage)
1000 cycles from -40°C to 125°C (Thermal Cycling)
1000 hours at 85°C / 85% RH (High Temp & Humidity)
