Kevlar vs. Twaron: Know the Difference
By Shumaila Saeed || Published on February 14, 2024
Kevlar is a heat-resistant, strong synthetic fiber, used in bulletproof vests; Twaron is a similar aramid fiber, often used interchangeably but with different manufacturing processes.
Key Differences
Kevlar, developed by DuPont in the 1960s, is renowned for its use in ballistic and stab-resistant body armor. Twaron, developed by AkzoNobel in the 1970s, shares many of Kevlar's properties but was introduced slightly later.

The production process of Kevlar involves an aramid polymer being extruded through a spinneret. Twaron, though similar in chemical structure, is produced through a process known as dry-jet wet spinning, resulting in slightly different fiber characteristics.
