Phase Change Thermal Pad Series: High-Performance Thermal Interface Solution
The LXPCM Series is a high-performance Phase Change Thermal Interface Material developed by Lixing Composite Material. Its core characteristic lies in its ability to soften progressively upon reaching the phase change temperature, allowing it to flow and fill microscopic air gaps and surface irregularities between heat-generating components and heat sinks.
Why Choose the LIXING Phase Change Thermal Pad?
Designed for high-end thermal management, the LXPCM series provides a reliable alternative to traditional thermal pads and grease:
Optimized Interface Filling: Softens at 45°C ~ 55°C to behave like a liquid, maximizing the contact area and minimizing contact resistance.
Ultra-Low Thermal Resistance: With a resistivity of only 0.08 °C·in²/W, it ensures rapid heat transfer for critical electronic components.
Robust Thermal Performance: Offers a thermal conductivity of 4 W/m·K, ideal for high-power density applications.
Long-Term Stability: Operates reliably from -40°C to 125°C without the drying or “pump-out” issues commonly found in thermal greases.
