With the launch of Tenax Next HTS45 E23 24K carbon fiber filament yarn at JEC World 2025, Teijin Carbon, a producer of carbon fibers and carbon fiber-based materials, showcases its pioneering spirit in combining innovation and sustainability. The new product offers a potential 35 percent CO₂ reduction over regular carbon fiber filament yarn manufactured with existing production processes, helping to meet increasing demand for sustainable, high-performance materials in the industrial, automotive and aerospace markets.

Tenax Next HTS45 E23 24K carbon fiber filament yarn is based on the renowned HTS (high tenacity) carbon fiber type, known for its excellent processability, heritage and credibility in industrial and aerospace markets. With a tensile strength of over 4800 MPa and a modulus of 240 GPa, Tenax Next HTS45 E23 24K provides a high-performance alternative with a substantially reduced environmental footprint.

Another milestone: Carbon fiber filament yarn is produced using renewable energy, with the option of sustainable raw materials. Additionally, Teijin Carbon is implementing new process technologies to further mitigate environmental impact.

“Teijin´s development of Tenax Next HTS45 E23 24K carbon fiber filament yarn, offering a significant CO2 saving for future advanced materials, has reshaped our expectations”, says Marc Fette, CEO of the CTC GmbH (an Airbus company). “It’s amazing to see a material that not only delivers outstanding performance but also aligns with our sustainability ambitions.”

Pioneering sustainability

Teijin Carbon established its carbon fiber production and supply system based on ISCC PLUS certification. The attractiveness of ISCC PLUS certification for Teijin Carbon is exemplified by the future production of sustainable carbon fibers.

Teijin Carbon uses various chemical building blocks to produce polyacrylonitrile, a synthetic, organic polymer widely used as the precursor to carbon fiber. While both conventional and sustainable raw materials can be purchased on the global market, in the future, Teijin Carbon intends to purchase more materials obtained through recycling or directly from bio-based sources. At JEC World, Teijin Carbon is presenting its first carbon fiber products that demonstrate significant progress in reducing CO₂ emissions and advancing circularity.
