LXPCM Phase Change Thermal Pad Series

Key Advantages

Overview: The LXPCM series phase change thermal pad combines the easy handling of a thermal pad with the ultra-low thermal resistance of thermal grease. At room temperature it is a solid sheet, easy to cut and place by automated assembly; when the device reaches the phase change temperature range, the material undergoes a physical phase change and fully wets the interface, expelling air gaps and delivering a thermal impedance of only 0.08 °C·in²/W. Compared with conventional thermal grease it does not pump out or dry-crack, greatly improving the service life and stability of electronic products.

Why it matters: Because the LXPCM Series Phase Change Thermal Pad stays solid until operating temperature, it ships, die-cuts and assembles like a pad yet performs like grease once in service, holding its minimum thermal resistivity of 0.08 °C·in²/W without pump-out or dry-out across the lifespan of high-performance electronics.

Phase Change Thermal Pad Series: Advanced Heat Dissipation and Interface Filling

Phase Change Thermal Pad Series: Premium Solution for Advanced Thermal Management

In high-end electronics processes that demand the ultimate in heat dissipation, the phase change thermal pad is a core consumable for maximizing heat-transfer efficiency. The LXPCM series high-performance phase change thermal interface material developed by Lixing Composite Materials softens once it reaches its phase change temperature, providing liquid-like gap filling that ensures full contact between the heat-generating component and the heat sink.

Why Choose the Lixing Phase Change Thermal Pad?

The LXPCM series phase change thermal pad has unique dynamic physical properties that overcome the interface thermal resistance challenges conventional thermal pads cannot:

  • Dynamic interface filling: Gradually softens above the phase change temperature (45°C ~ 55°C), flowing like a liquid to penetrate and fill the fine irregularities between heat-dissipating surfaces.

  • Very low interface thermal resistance: Thermal impedance of only 0.08 °C·in²/W rapidly conducts heat from the chip to the thermal module, improving system stability.

  • High thermal conductivity: A stable thermal conductivity of 4W/mk suits high heat-load environments such as high-power modules and servers.

  • Outstanding reliability: Wide operating temperature range (-40°C ~ 125°C); it neither dries out and cracks nor sags under long-term thermal cycling, maintaining excellent physical properties.
