Zylon® Fiber

Zylon® Fiber

Zylon® (PBO fiber) is a super fiber with strength and modulus that almost doubles p-Aramid fiber.  Zylon has superior creep resistant to p-Aramid fibers and is very heat resistant, with a decomposition Temperature of 650°C (1202°F) and has extremely high flame resistance.   Zylon is not light resistant and shows a decrease in strength with exposure to sunlight.  Zylon products for outdoor use have to be protected by convering materials.


Zylon® Fiber Properties:

  • Highest tensile strength and tensile modulus among high-performance fibers
