• New Therma-Tech™ Thermally Conductive technologies with natural graphite offer high thermal conductivity and cost efficiency for LED lighting, automotive heat sinks, and heat exchange system applications
• Eight new grades engineered to replace metal components such as aluminum, delivering weight reduction, corrosion resistance, and increased design freedom through standard injection molding

POMMERLOCH, Luxembourg — June 2, 2026 – Avient Corporation, an innovator of materials solutions, today announced the expansion of its Therma Tech™ product portfolio with eight new thermally conductive grades that leverage natural graphite to deliver high thermal conductivity and cost efficiency for applications such as LED lighting, automotive heat sinks, and heat exchange systems. Natural graphite offers a lower product carbon footprint and typically requires less energy to produce than synthetic graphite, while still maintaining thermal conductivity performance. This expansion addresses the growing demand for efficient heat management across multiple end markets while including select grades with post-industrial recycled (PIR) content options to support sustainability goals.

What the Expanded Therma-Tech™ Portfolio Offers
As electrification accelerates across transportation, industrial equipment, appliance, and electronics sectors, engineers face mounting pressure to manage heat more efficiently, more cost-effectively, and with less weight. Metal components such as aluminum heat sinks and die-cast enclosures remain a standard approach — but they carry inherent limitations: added mass, susceptibility to corrosion, complex manufacturing processes, and constrained design freedom. For original equipment manufacturers (OEMs) and product designers pursuing lightweighting strategies, metal-to-plastic conversion in thermal management applications is no longer a future possibility; it is an active engineering priority.

“Our customers are looking for ways to manage heat more efficiently without compromising performance or sustainability goals,” said Hermann Fuechter, Senior Manager, Global Strategic Marketing, Specialty Engineered Materials at Avient. “By incorporating natural graphite into our Therma Tech™ portfolio, we’re giving designers greater flexibility to reduce system costs while delivering the thermal and mechanical properties they require.”

Eight New Natural Graphite-Based Grades Expand Practical Access to Thermally Conductive Polymers
The expanded Therma-Tech™ portfolio can address the thermal management challenges facing engineers across transportation, appliance, electronics, and healthcare end markets. Key attributes include:

• High thermal conductivity enabled by natural graphite-based technology, delivering performance competitive with more costly specialty filler systems
• Improved cost efficiency compared to existing high-performance thermally conductive technologies — making polymer-based thermal management viable for mid-tier production volumes and cost-sensitive applications
• Thermal performance and design flexibility maintained from existing Therma-Tech™ grades, enabling drop-in evaluation against current metal or thermally conductive polymer specifications
• Compatibility with standard injection molding processes, limiting the need for specialized manufacturing equipment

Applications Driving Demand for Thermally Conductive Polymer Technologies
The new natural graphite-based Therma-Tech™ grades can be used for end-use applications where thermal management, weight, and design flexibility are primary engineering requirements:

• LED lighting assemblies — heat sinks and thermal interface components requiring thermal management at reduced mass and component cost
• Automotive heat sinks — thermal management components for electrified powertrains, battery thermal management systems, and onboard electronics
• Heat exchange systems — components in HVAC, industrial, and appliance heat exchangers
• Electronics and appliance housings — thermally active housings where integrated thermal management reduces system complexity
• Healthcare devices — thermally managed device housings and components requiring biocompatibility and processing reliability

Therma-Tech™ Technologies at FIP and Equiplast 2026
Avient will feature Therma-Tech™ thermally conductive technologies at two major European trade shows running concurrently June 2–5:

• FIP — France Innovation Plasturgie | Eurexpo, Lyon, France | Booth C55 
• Equiplast | Gran Via Venue, Fira Barcelona, Barcelona, Spain | Booth 95 

Avient technical specialists will be available at both shows to discuss the expanded Therma-Tech™ portfolio, application opportunities, and sampling. For more information, visit www.avient.com.
