Aramid Fiber
ALKEX®, short for aromatic polyamide, is a high-performance synthetic fiber developed by HS Hyosung Advanced Materials using proprietary technology. Known as the "golden fiber" due to its light-yellow hue, aramid fiber offers exceptional heat resistance and strength — with tensile strength five times greater than steel — making it an essential material in defense, industrial, and high-performance applications.
Engineered for Protection, Trusted by Industries Worldwide
ALKEX® is a para-aramid fiber originally developed in 2003 and successfully commercialized in 2009. Its superior tensile strength and outstanding resistance to heat (withstanding temperatures over 500°C), abrasion, impact, and chemicals make it an ideal material for ballistic protection and reinforcement. This ultra-durable fiber is so strong that even bullets cannot penetrate it, and yet it remains lightweight and flexible — durable enough to protect soldiers and, hypothetically, superheroes alike.

ALKEX® in Action: From Bulletproof Vests to Electric Vehicles
Aramid fiber’s robust and resilient characteristics have earned ALKEX® accolades at major defense exhibitions like Milipol Paris, where bulletproof vests and helmets made from this fiber were showcased. In the age of electrification and 5G, ALKEX® is now also being recognized as a critical material for lightweight EV components and durable fiber optic cables.
With the defense markets increasing demand for ballistic materials and the expanding need for lightweight, high-strength reinforcement in next-gen vehicles and telecom, ALKEX® continues to solidify its role as a market-defining solution.
