Manufactures liquid-metal thermal interface materials
Overview
Boston Materials develops and manufactures advanced energy-transfer composites for high-performance electronics, aerospace, and electrified mobility. Its Liquid Metal ZRT® uses vertically oriented carbon fibers embedded in a liquid metal matrix to create a drop-in thermal interface that conducts heat efficiently between components, and is designed for seamless integration into automated assembly. The company differentiates itself by combining Z-axis carbon fiber reinforcement with a liquid metal matrix and scaling via roll-to-roll production using reclaimed carbon fiber, enabling multiple applications from a single platform. Its goal is to scale production to meet industrial demand across semiconductor, aerospace, and electrified-vehicle markets while expanding sustainability through recycled carbon fiber use.

Simplify's Take
What believers are saying
- Mitsubishi Chemical invested via Diamond Edge Ventures for AI data center thermal solutions.
- Raised $13.5M from AccelR8, Valo Ventures to expand semiconductor manufacturing in 2026.
- 60-inch-wide roll-to-roll production scales ZRT films with PEEK, PEI polymers.
What critics are saying
- Intel's Direct Die Cooling eliminates TIMs like ZRT in Lunar Lake processors by Q2 2026.
- Nvidia GB200 racks deploy integrated liquid cooling, obsoleting drop-in ZRT preforms in Q3 2026.
- $2M debt at 12-15% interest forces dilution as capex exceeds $13.5M raise by mid-2027.
What makes Boston Materials unique
- Liquid Metal ZRT® delivers 5-8°C cooling improvement over thermal greases in data center GPUs.
- ZRT interlaminar films mitigate delamination in aerospace composites using Z-axis Fiber™.
- Z-axis carbon fiber enables lightweight bipolar plates for hydrogen fuel cells from recycled fiber.

↓ -3%Mitsubishi Chemical Group and Boston Materials have announced a strategic collaboration to advance thermal management solutions for high-performance computing and AI data centres. The partnership includes an investment in Boston Materials from Mitsubishi's US-based corporate venture capital arm, Diamond Edge Ventures. The companies will develop the second-generation Liquid Metal ZRT product, a thermal interface material using Boston Materials' patented Z-axis Carbon Fibre technology and proprietary liquid metal alloys. Boston Materials will leverage Mitsubishi Chemical Group's supply chain for high-performance electronic materials. The collaboration aims to address thermal management challenges in semiconductor packaging for data centre applications.
Boston Materials, based in Billerica, MA, raised $13.5M in funding led by AccelR8 and Diamond Edge Ventures, with participation from Valo Ventures, Gatemore Venture Partners, Collab Fund, and Woori Venture Partners. The company plans to use the funds to expand into the semiconductor market, leveraging its Z-axis Fiber™ technology.
