Key Differences
Kevlar and Twaron are both high-strength, heat-resistant aramid fibers utilized in various applications.
Kevlar, a product of the American company DuPont, has become synonymous with bulletproof vests due to its remarkable tensile strength. On the other hand, Twaron, which originates from the Dutch company Teijin, shares many properties with Kevlar and is likewise used in protective gear. Both fibers are exceptional in their resistance to heat, chemicals, and wear. This makes them prime candidates for applications in aerospace, military, and automotive industries.
Kevlar and Twaron, while comparable in function and characteristics, arise from distinct manufacturing processes and have nuanced differences in their properties.
As a result, they may be chosen for different applications based on specific requirements. Overall, while Kevlar might be the more globally recognized name, Twaron stands as a formidable counterpart in the realm of aramid fibers.

Kevlar
Kevlar (para-aramid) is a heat-resistant and strong synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Twaron
Twaron (a brand name of Teijin Aramid) is a para-aramid. It is a heat-resistant and strong synthetic fibre developed in the early 1970s by the Dutch company Akzo Nobel's division Enka BV, later Akzo Industrial Fibers.
Kevlar
(uncountable) (Fabric, cordage, etc made of) aramid fiber, an exceptionally strong, light, man-made fibre used to strengthen cables and sheet materials, e.g. in stab-resistant vests.
Kevlar
