Easy-to-integrate thermal protection

Fiber properties

Teijinconex® offers excellent heat resistance compared to other synthetic fibers. Also, its mechanical properties are comparable with existing general-purpose synthetic fibers, such as polyester and natural organic fibers. It’s easy to process, offers a high degree of flexibility, and feels softer than other para-aramids.

Flame-resistant properties of Teijinconex®

Flame resistant

Teijinconex® is inherently flame and heat resistant up to 400 °C – a property that doesn’t diminish with repeated laundering. It doesn’t burn or melt either, so protective clothing made with Teijinconex® won’t stick to skin.

Thermal protection

Teijinconex® has a low thermal conductivity coefficient, with typically 0.04–0.05 W/m K (measured in a fabric). This means Teijinconex®-based protective clothing shields wearers from the heat of the flame, minimizing skin damage.
