Natural graphite-based thermally conductive grades: New launches by Avient
Last update on Jun 5, 2026
Efficient heat management remains a growing challenge as electrification advances across transportation, industrial equipment, appliances, and electronics. At the same time, engineers are under pressure to reduce weight, control costs, and maintain design flexibility. To address these requirements, Avient Corporation has expanded its Therma Tech™ portfolio with eight new thermally conductive grades based on natural graphite technology.

Requires less energy and offers lower footprint
The new grades are designed for applications including LED lighting, automotive heat sinks, and heat exchange systems. According to the company, natural graphite delivers high thermal conductivity while offering a lower product carbon footprint and typically requiring less energy to produce than synthetic graphite. Select grades also include post-industrial recycled (PIR) content options to support sustainability goals.
Traditional thermal management solutions often rely on aluminum heat sinks and die-cast metal enclosures. While widely used, these materials can add weight, be susceptible to corrosion, involve complex manufacturing processes, and limit design flexibility. As a result, metal-to-plastic conversion has become an increasingly important engineering strategy for original equipment manufacturers and product designers seeking lightweight thermal management solutions.
“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.”
Key properties
According to Avient, 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
Avient states that 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
At FIP and Equiplast 2026
Avient is showcasing Therma-Tech™ thermally conductive technologies at two 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
You can review grades from Therma-Tech™ portfolio and compare technical properties in the Master Catalog of Plastics.
