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.

KAMPALA, Uganda (AP) — Uganda’s presidential election was plagued by widespread delays Thursday in addition to a days-long internet shutdown that has been criticized as an anti-democratic tactic in a country where the president has held office since 1986.

Some polling stations remained closed for up to four hours after the scheduled 7 a.m. start time due to “technical challenges," according to the nation's electoral commission, which asked polling officers to use paper registration records to ensure the difficulties did not “disenfranchise any voter.”

President Yoweri Museveni, 81, faces seven other candidates, including Robert Kyagulanyi, a musician-turned-politician best known as Bobi Wine, who is calling for political change.

The East African country of roughly 45 million people has 21.6 million registered voters. Polls were expected to close at 4 p.m., but voting was extended one hour until 5 p.m. local time. Results are constitutionally required to be announced in 48 hours.

In the morning, impatient crowds gathered outside polling stations expressing concerns over the delays. Umaru Mutyaba, a polling agent for a parliamentary candidate, said it was “frustrating” to be waiting outside a station in the capital Kampala.

“We can’t be standing here waiting to vote as if we have nothing else to do," he said.

Wine, the candidate, alleged electoral fraud, noting that biometric voter identification machines were not working at polling places and claiming that there was “ballot stuffing.”

Wine wrote in a post on X that his party's leaders had been arrested. “Many of our polling agents and supervisors abducted, and others chased off polling stations,” the post said.

Museveni told journalists he was notified that biometric machines weren't working at some stations and that he supported the electoral body's decision to revert to paper registration records. He did not comment on allegations of fraud.

Ssemujju Nganda, a prominent opposition figure and lawmaker seeking reelection in Kira municipality, told The Associated Press he had been waiting in line to vote for three hours.

Nganda said the delays likely would lead to apathy and low turnout in urban areas where the opposition has substantial support. "It’s going to be chaos,” he said.

Nicholas Sengoba, an independent analyst and newspaper columnist, said delays to the start of voting in urban, opposition areas favored the ruling party.

Emmanuel Tusiime, a young man who was among dozens prevented from entering a polling station in Kampala past closing time said the officials had prevented him from participating.

“My vote has not been counted, and, as you can see, I am not alone," he said he was left feeling “very disappointed.”

Uganda has not witnessed a peaceful transfer of presidential power since independence from British colonial rule six decades ago.

Museveni has served the third-longest term of any African leader and is seeking to extend his rule into a fifth decade. The aging president’s authority has become increasingly dependent on the military led by his son, Muhoozi Kainerugaba.

Museveni and Wine are reprising their rivalry from the previous election in 2021, when Wine appealed to mostly young people in urban areas. With voter turnout of 59%, Wine secured 35% of the ballots against Museveni’s 58%, the president’s smallest vote share since his first electoral campaign three decades ago.

The lead-up to Thursday's election produced concerns about transparency, the possibility of hereditary rule, military interference and possible vote tampering.

Uganda's internet was shut down Tuesday by the government communications agency, which cited misinformation, electoral fraud and incitement of violence. The shutdown has affected the public and disrupted critical sectors such as banking.

There has been heavy security leading up to voting, including military units deployed on the streets this week.

Amnesty International said security forces are engaging in a “brutal campaign of repression,” citing a Nov. 28 opposition rally in eastern Uganda where the military blocked exits and opened fire on supporters, killing one person.

Museveni urged voters to come out in large numbers during his final rally Tuesday.

“You go and vote, anybody who tries to interfere with your freedom will be crushed. I am telling you this. We are ready to put an end to this indiscipline,” he said.

The national electoral commission chairperson, Simon Byabakama, urged tolerance among Ugandans as they vote.

“Let us keep the peace that we have,” Byabakama said late Wednesday. “Let us be civil. Let us be courteous. Let’s be tolerant. Even if you know that this person does not support (your) candidate, please give him or her room or opportunity to go and exercise his or her constitutional right."

Authorities also suspended the activities of several civic groups during the campaign season. That Group, a prominent media watchdog, closed its office Wednesday after the interior ministry alleged in a letter that the group was involved in activities “prejudicial to the security and laws of Uganda.”
