About HS Hyosung Advanced Materials

HS Hyosung Advanced Materials is the global leader in polyester tire cord, the reinforcement fabric inside tires, and supplies major tire manufacturers worldwide. Its portfolio extends to steel cord, airbag fabrics, seatbelt yarn, and newer specialty lines including aramid fiber and carbon fiber for industrial and mobility applications. Originally spun out of Hyosung Corp's operating divisions, the company now sits within the HS Hyosung wing that emerged when the founding family divided the broader Hyosung group. Plants across Asia, Europe, and the Americas allow it to serve tire makers locally.

Tire reinforcement demand follows global vehicle use and replacement-tire cycles, giving the core business a steadier cadence than new-car production alone, though it remains cyclical and export-driven. Relationships with a concentrated set of global tire makers are a structural dependency. The carbon fiber and aramid lines are the optionality investors weigh, since they target hydrogen tanks, cables, and other industrial uses with different economics. Governance analysis now runs through the HS Hyosung group structure formed by the founding family's separation of the conglomerate.

The company's core business dates to 1968, when Hyosung predecessor Tongyang Nylon became the first Korean producer of nylon tire cord, a product the firm later came to dominate worldwide in polyester form. The industrial materials operations were separated into a standalone listed company, Hyosung Advanced Materials, during the group's 2018 breakup of Hyosung Corporation into holding and operating companies. Along the way the business added steel cord, airbag fabrics through the acquisition of Global Safety Textiles, and development programs in aramid and carbon fiber. When the founding family divided the conglomerate in 2024, the company moved into the newly formed HS Hyosung group led by Cho Hyun-sang, adopting its current name.

Tire cord economics reward incumbency. Tire makers qualify a supplier's material through lengthy testing before designing it into products, then sign multi-year arrangements, so switching is rare and proven reliability commands lasting loyalty. The company runs an integrated chain from polymer through spinning to treated cord fabric, supporting both cost control and the uniform quality tire plants demand. Steel cord and bead wire deepen its content per tire, while airbag fabrics and seatbelt yarn diversify the portfolio within vehicle safety. Carbon fiber, branded TANSOME, targets hydrogen storage vessels and industrial equipment where few certified producers compete, and aramid serves protective and friction applications.
