Mitsubishi Chemical Group(MCG) and Boston Materials Forge Strategic Alliance on Liquid Metal Thermal Materials for Next-Gen Semiconductors.
Inside the Strategic Collaboration
Mitsubishi Chemical Group has entered into a strategic collaboration with Boston Materials to co-develop advanced liquid metal-based thermal interface materials targeting high-performance computing and artificial intelligence semiconductor packages.
The alliance combines Mitsubishi Chemical Group’s global materials footprint and investment arm with Boston Materials’ expertise in energy transfer and thermal management solutions to accelerate commercialization of next-generation thermal interface materials for data centers and other high-power electronics.
Focus on Liquid Metal ZRT Technology
At the core of the partnership is the second-generation Liquid Metal ZRT thermal interface material, which builds on Boston Materials’ patented Z-axis Carbon Fiber architecture integrated with proprietary liquid metal alloys.
This architecture is designed to deliver significantly higher heat transfer efficiency at the chip and package level, directly addressing the thermal bottlenecks in AI accelerators, GPUs and high-power ASICs operating at kilowatt-class power densities.
Boston Materials has already brought its first-generation Liquid Metal ZRT product, LMZ1100, to market, where it has demonstrated more than a 10°C reduction in device temperatures in liquid-cooled, high-power ASIC and GPU applications.
The material has shown strong reliability under continuous operation and is compatible with high-volume manufacturing processes, making it suitable for large-scale deployment in hyperscale and enterprise data centers.
Strategic APAC Expansion
For Mitsubishi Chemical Group, the collaboration fits into a broader strategy to expand its semiconductor materials portfolio and position itself as a key supplier of high-performance functional materials to the chip industry.
The company plans to establish advanced semiconductor packaging integration and application development labs across Asia to support qualification, application engineering and mass adoption of the next-generation Liquid Metal ZRT materials, with a particular focus on the Asia-Pacific manufacturing base.
Key Comments
Executives at Mitsubishi Chemical Group emphasize that traditional scaling is no longer sufficient to unlock further semiconductor performance gains, with thermal management now one of the most critical constraints in AI and HPC system design.
Internal commentary from the company underscores that the decision to partner with Boston Materials followed extensive benchmarking of Liquid Metal ZRT against incumbent and emerging thermal solutions, with the technology selected for its superior performance profile and fit with Mitsubishi Chemical Group’s long-term semiconductor strategy.
Leadership at Boston Materials highlights that the explosive growth of AI infrastructure has made advanced thermal interface materials a strategic enabler for the entire compute stack. The company notes that collaborating with a global player like Mitsubishi Chemical Group will not only accelerate the development of second-generation Liquid Metal ZRT products but also open up broader access to high-volume semiconductor packaging ecosystems worldwide, allowing customers to push power density and reliability targets beyond what current thermal solutions can support.
