Enhancing energy efficiency and durability, XCM’s high-performance thermal materials 

XTIM

XTIM (XCM Thermal Interface Material) is a high-performance thermal management material developed by XCM using its proprietary electrically insulated graphite (EIG). 

It is formulated by blending ceramic and carbon-based fillers in an optimized ratio to achieve superior thermal performance. 

With its low-viscosity property, XTIM uniformly penetrates into complex-shaped heat-generating components, maximizing thermal dissipation efficiency. 

In addition, compared to conventional alumina (Al₂O₃)-based materials, XTIM is lighter, has a lower specific gravity, and delivers superior thermal conductivity, making it suitable for advanced industries such as EV chargers, data centers, and AI robots.

Product Features 

Excellent Thermal Conductivity 
Up to 15% higher thermal conductivity compared to conventional alumina (Al2O3), allowing rapid heat dissipation from heat-generating components. 
Excellent Adaptability to Complex Shapes 
With its low-viscosity property, it penetrates and adheres evenly to complex structures, maximizing heat transfer efficiency. 


Optimized for Lightweight Design 
Up to 20% reduction in weight and density compared to equivalent performance materials, enabling lighter
