Asahi Kasei to unveil PFAS-free polyamide and CFRP recycling technology at K 2025

Diversified global manufacturer Asahi Kasei will unveil its newest innovation in PFAS-free polyamide (PA) and recycling technology of continuous carbon fibers at K 2025 in Hall 8a, Booth E23. The company will also showcase its diverse material solutions for automotive applications, improved connectivity, and lightweighting. K 2025, considered the world's No. 1 trade fair for plastics and rubber, will take place during October 8–15, 2025, in Düsseldorf, Germany.

Asahi Kasei has developed a groundbreaking recycling technology that enables the recovery of continuous carbon fibers from CFRP (carbon fiber reinforced plastic) pressure vessels used in automobiles. Utilizing electrolyzed sulfuric acid, the process completely decomposes the resin matrix while preserving the carbon fibers' original strength and continuous structure. Unlike conventional recycling methods that result in chopped fibers, this technology allows for the perpetual recycling of high-quality, cost-effective continuous carbon fibers from CFRP pressure vessels. At K 2025, Asahi Kasei will showcase over 200 meters of recycled continuous carbon fiber.

Asahi Kasei will also display PA and SEBS (hydrogenated styrene-based thermoplastic elastomer) compounds utilizing a bio-based and biodegradable cellulose nanofiber (CNF). This material is made from cotton linter and has high heat resistance and network-forming ability. CNF-reinforced polyamide becomes less viscous when agitated, making it highly suitable for 3D printing applications for easy printing, dimensional accuracy, smooth appearance, and mechanical performance. CNF-reinforced SEBS features a unique softness, which can be adjusted by changing the internal structure of the molded product. In addition, it shows a very low warpage and shrinkage, and good hydrolysis resistance. These properties make this material suitable for a wide range of applications, for example, jigs & tooling or prosthetics & orthotics devices.

In response to the increasing demand for PFAS-free materials, Asahi Kasei is developing a PFAS-free low-friction LEONA™

 PA and will introduce the new grade for the first time in Europe. Based on internal evaluations, the material has the same low-friction properties as fluororesin, making it suitable for sliding applications in various industries, including automotive, robot parts, office equipment parts, and sporting goods.

 

Materials for lightweighting and streamlined production of automotive parts

There has been a growing emphasis on reduced weight and improved design in automotive manufacturing. Asahi Kasei will display various technologies to address the most pressing concerns of automotive manufacturers at K 2025. One such solution is AZP™ transparent polymer

 featuring almost no birefringence and light weight. It overcomes the challenges of conventional transparent polymers in applications with polarizing light, such as virtual reality and augmented reality devices and automotive head-up displays (HUD), while maintaining superior processability for large-scale production of injection-molded optical components. The company will exhibit an interactive automotive demonstration at K 2025 to showcase how AZP™ contributes to next-generation HUD.

Conventional approaches to automotive instrument panels, door panels, armrests, or center consoles have used different materials and production technologies for skin, foam, and core layers. Asahi Kasei’s SEBS

 material is suitable for skin and foam layers, which can be molded in one step by utilizing a core back injection molding process, with strong chemical bonding between all the layers to eliminate the need for additional adhesive layers. SEBS contributes to reducing the total number of materials, simplifying the manufacturing process, and improving the recyclability of interior components.

Another solution from Asahi Kasei that streamlines the manufacturing process for OEMs is SunForce™ mPPE (modified polyphenylene ether) particle foam beads. This material is well-suited to mass production of thin-walled, complex-shaped parts that require low tolerances, high heat stability, or UL94 V-0 flame retardancy. These properties make SunForce™ a perfect fit for thermal management solutions in electronic devices, transportation trays for Li-ion battery cells, insulation parts for HVAC equipment, and foam cores for FRP composite parts.

With the increasing number of radar applications across industries, the pressure to reduce material, production costs, and weight is rising. Slotted waveguide array antennas for automotive millimeter-wave radars are typically made of metal, requiring costly and time-consuming milling processes. Asahi Kasei’s XYRON™

 mPPE features proven wet-platability, omitting the milling process and allowing for mass production of resin antenna parts via injection molding, which lowers cost and increases scalability.

Solar Trees Could Save Forests From Deforestation While Generating the Same Power as Solar Farms

Picture a forested hillside stripped bare, replaced by row after row of black solar panels. That’s the tradeoff many communities face: renewable power at the cost of ecosystems. But a growing body of research suggests it doesn’t have to be that way. The solution may look less like an industrial solar farm and more like a forest solar trees.

Researcher Dan-Bi Um at the Korea Maritime Institute compared conventional flat-panel arrays with solar trees structures designed to mimic real trees, with panels branching upward like leaves. Their results were startling. “Linear arrangements of these structures achieve superior power capacity compared to conventional fixed panels while preserving existing forest cover,” the team reports.

Why Trees Make Better Solar Farms

Unlike ground-mounted panels that demand clearcuts, #solartrees are built and installed vertically into the canopy. This design allows light to filter down to understory plants while still capturing energy above. In simulations using Google Earth satellite imagery, Dan-Bi Um found that solar trees preserved 99% of the forest, compared to just 2% left standing when flat-panel plants were installed. All without sacrificing power output.

Conventional #solarfarms need a lot of land. In #SouthKorea, that’s meant cutting forests to install large arrays of flat-panel plants, a process that “completely destroy the biodiversity of the #forestecosystem,” Um warns. Between 2016 and 2018, deforestation tied to solar farms in the country more than quadrupled.

Solar trees sidestep #deforestation. By placing them along hiking trails or forest boundaries at 20-meter intervals, the researchers showed that 63 trees outfitted with high-efficiency panels could match the one-megawatt capacity of a conventional plant all while leaving the forest intact.

The advantages, of course, go beyond forests. In cities, solar trees provide shade for pedestrians and cars while generating #cleanelectricity. Some models include charging ports for electric vehicles or benches equipped with wireless charging . Researchers also note their cooling effect in urban “heat island” zones, where rising summer temperatures threaten public health.

The Bigger Picture:

This research arrives at a critical moment. Nations have pledged at recent climate summits to triple renewable energy capacity by 2030 while halting deforestation. The problem is that those goals often collide. In South Korea, deforestation tied to solar projects surged from 529 hectares in 2016 to 2,443 hectares in 2018. Similar conflicts play out worldwide, from the Amazon to Appalachia.
