The Fiber

PyroTex® is an engineered Acrylic fiber and clearly surpasses currently accepted standards. Because of its inherent properties it is not comparable to any of the other FR fibers on the market. For example:

  • Flame resistant – the LOI is 43%
  • Acid and Alkaline resistant
  • UV resistant
  • Resistant against solvents, hydrolysis and oxidizing agents
  • Heat resistant up to 250°C (480°F)  
  • Anti-bacterial

Other properties of PyroTex® are:

  • does not melt nor drip
  • does not smoke
  • does not produce toxic fumes
  • is dyeable (also available in dope dyed) → PyroTex® coloured



  • Oeko-Tex Standard 100 Class 1
  • REACH → pass
  • CPSIA → pass
  • Berry Amendment
  • compliant

 We neither use antimony nor halogens nor phosphorus in our process!
