Asahi Kasei to Unveil PFAS-Free Polyamides and CFRP Recycling Technology at K 2025

DUESSELDORF, Germany--(BUSINESS WIRE)--Sep 3, 2025--

Japanese technology company Asahi Kasei will unveil its newest innovation in PFAS-free polyamides and recycling technology of continuous carbon fibers at K 2025 in Hall 8a, Booth E23. The company will also showcase its diversified material solutions for automotive applications, improved connectivity and lightweighting. K 2025 is considered the world's No. 1 trade fair for plastics and rubber and will take place from 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 plastics) 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 the K Show, Asahi Kasei will showcase over 200 meters of recycled continuous carbon fiber.

Asahi Kasei will also display PA and SEBS compounds utilizing a bio-based and biodegradable cellulose nano fiber (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™ polyamide 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 fluororesins, making it suitable for sliding applications in various industries, including automotive, robot parts, OA 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 the transparent polymer, AZP™, which features an almost zero birefringence at a lightweight. It overcomes the challenges of conventional transparent polymers in applications with polarizing light, such as Virtual & 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 and the strong chemical bonding between all layers eliminates 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 to streamlining the manufacturing process for OEMs from Asahi Kasei is the mPPE (modified polyphenylene ether) particle foam, SunForce™. This material is well-suited for 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 HVACs, 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 cost- and time-intensive milling processes. Asahi Kasei’s mPPE XYRON™ features proven wet-platability, omitting the milling process and allowing for mass production of resin antenna parts via injection moulding which lowers cost and increases scalability.

Asahi Kasei will exhibit in Hall 8a, Booth E23. For more information, visit the dedicated landing page: https://k-2025.asahi-kasei.eu/de.

WASHINGTON (AP) — The Freedom 250 Grand Prix is largely about the visuals — the Capitol hovering behind Turn 1, the Washington Monument off in the distance.

Now, IndyCar drivers can finally evaluate the actual track.

“I didn’t know if it was going to be fun or not to drive. It’s a blast, super fun,” series points leader Alex Palou said after a morning practice session Saturday. “Very bumpy, huge bumps heading into Turn 2 and Turn 6. Massive bumps that are going to spice things up.”

The 1.7-mile street course in downtown Washington was an unknown commodity, set up for the first — and possibly the last — time for this event celebrating the country's 250th birthday. As these tracks go, it looks pretty simple with only seven turns, all but one to the left.

That doesn't mean the driving is smooth, though — even on the straightaway down Pennsylvania Avenue between Turns 1 and 2.

“We got quite a bit of bumps on the exit of Turn 1, quite a bit of bumps going into 2, the straightaway,” said Pato O'Ward, who won last month at Mid-Ohio. “I would say that’s taken over a little bit of what the characteristic of what this track is.”

Pennsylvania Avenue is repaved often because of its role in presidential inaugurations. Race chair Bud Denker spoke highly of the area's roads in the run-up to the event, but at high speed, the slightest bump can make a difference. Louis Foster went over one near the end of the Independence Avenue straightaway and ended up going nose-first into the wall — in the area Palou was talking about before Turn 6.

“Going to try to see if we can get a better balance in the corners, not focus so much on the bumps. They’re not going to disappear,” Palou said. “I think if you move a little bit on lanes, might be a little bit better, but it’s not going to completely go away from that.”

Palou said Turn 2 — a severe bend at the end of the Pennsylvania Avenue straightaway — presents a good passing opportunity. Same for Turn 5 — a 90-degree left from 7th Street onto Independence Avenue.

“I think there’s going to be a lot of action. I see that just having a wide track, it’s just going to allow us to have more passing than, for example, Detroit,” Palou said, referring to another downtown Indycar course. “It’s so narrow that even if you are so much faster, you can just block so much easier. Here, if you’re not going to have the pace, they’re going to overtake you.”

Palou had the top practice lap of 56.6145 seconds in the second session, then topped qualifying later in the day.

Although IndyCar owns the D.C. spotlight this weekend, NASCAR made its presence felt when four-time Cup champion Jeff Gordon swept Saturday's two-race IROC event in Washington. Kurt Busch was runner-up in both races.

“I was like a kid in a candy store,” Busch said. “It was like I was in a bowl of M&M's with all the colors and the banners. ‘Where’s my braking zone? I don't know — oh, that's a cool building.'”

The weather was mostly fine despite some threatening clouds. IndyCar drivers can expect humid conditions for Sunday's 147-lap, 250-mile race.

“It’s going to be physical,” O'Ward said. “Every challenge that a street course usually throws at you. It’s bumpy. You got a bunch of sweat inside of the helmet. You’re bouncing up and down in there. It gets pretty rough, gets pretty aggressive.”
