PyroTex® is an engineered acrylic fiber with a limiting oxygen index (LOI) of 43% and a continuous running temperature of 250°C (480°F). It is acid, alkali, UV and hydrolysis resistant. It is not thermoplastic and therefore does not melt or drip.
None of the common FR agents such as antimony, halogens or phosphorous are used and as such no toxic fumes are emitted.
Additionally PyroTex® is permanently anti-bacterial.
The fiber is certified Class I according to Oeko-Tex Standard 100, can be used in nonwovens as well as in spun yarns and is available in 2,0/2,8/3,8dtex (1.9/2.5/3.5den) and cut lengths between 20-120mm (0.8-4.0in).
PyroTex® was the first fiber to combine all these properties into one which provided the industry with new possibilities in their product development.
Today PyroTex® is providing safety in airplanes as fire-blocker, comfort and protection as base-layer and outer shell for apparel applications and heat resistance for hotgas filters to only name a few of the ever growing products using PyroTex®.
Now also available as a new generation fire blanket.
